Let's suppose for the moment that the input consists of pairwise distinct primes, e.g., 2, 3, 5, and 7. Then the answer (for summing all sets, where the LCM of 0 integers is 1) is

\n\n
(1 + 2) (1 + 3) (1 + 5) (1 + 7),\n

because the LCM of a subset is exactly equal to the product here, so just multiply it out.

Let's relax the restriction that the primes be pairwise distinct. If we have an input like 2, 2, 3, 3, 3, and 5, then the multiplication looks like

\n\n
(1 + (2^2 - 1) 2) (1 + (2^3 - 1) 3) (1 + (2^1 - 1) 5),\n
\n\n

because 2 appears with multiplicity 2, and 3 appears with multiplicity 3, and 5 appears with multiplicity 1. With respect to, e.g., just the set of 3s, there are 2^3 - 1 ways to choose a subset that includes a 3, and 1 way to choose the empty set.

\n\n

Call a prime small if it's 19 or less and large otherwise. Note that integers 500 or less are divisible by at most one large prime (with multiplicity). The small primes are more problematic. What we're going to do is to compute, for each possible small portion of the prime factorization of the LCM (i.e., one of the ~70,000 states), the sum of LCMs for the problem derived by discarding the integers that could not divide such an LCM and leaving only the large prime factor (or 1) for the other integers.

\n\n

For example, if the input is 2, 30, 41, 46, and 51, and the state is 2, then we retain 2 as 1, discard 30 (= 2 * 3 * 5; 3 and 5 are small), retain 41 as 41 (41 is large), retain 46 as 23 (= 2 * 23; 23 is large), and discard 51 (= 3 * 17; 3 and 17 are small). Now, we compute the sum of LCMs using the previously described technique. Use inclusion-exclusion to get rid of the subsets whose LCM whose small portion properly divides the state instead of being exactly equal. Maybe I'll work a complete example later.

Discussion

\n\n

After reading the actual contest description (page 10 or 11) and the solution sketch, I have to conclude the author of the solution sketch is quite imprecise in their writing.

\n\n

The high level problem is to calculate an expected lifetime if components are chosen randomly by fair coin toss. This is what's leading to computing the LCM of all subsets -- all subsets effectively represent the sample space. You could end up with any possible set of components. The failure time for the device is based on the LCM of the set. The expected lifetime is therefore the average of the LCM of all sets.

\n\n

Note that this ought to include the LCM of sets with only one item (in which case we'd assume the LCM to be the element itself). The solution sketch seems to sabotage, perhaps because they handled it in a less elegant manner.

\n\n

What is meant by these states?

\n\n

The sketch author only uses the word state twice, but apparently manages to switch meanings. In the first use of the word state it appears they're talking about a possible selection of components. In the second use they're likely talking about possible failure times. They're could be muddling this terminology because their dynamic programming solution initializes values from one use of the word and the recurrence relation stems from the other.

\n\n

Does dp stand for dynamic programming?

\n\n

I would say either it does or it's a coincidence as the solution sketch seems to heavily imply dynamic programming.

\n\n

If so, what recurrence relation is being solved? How is dp[i] computed from dp[i-1]?

\n\n

All I can think is that in their solution, state i represents a time to failure , T(i), with the number of times this time to failure has been counted, dp[i]. The resulting sum would be to sum all dp[i] * T(i).

\n\n

dp[i][0] would then be the failure times counted for only the first component. dp[i][1] would then be the failure times counted for the first and second component. dp[i][2] would be for the first, second, and third. Etc..

\n\n

Initialize dp[i][0] with zeroes except for dp[T(c)][0] (where c is the first component considered) which should be 1 (since this component's failure time has been counted once so far).

\n\n

To populate dp[i][n] from dp[i][n-1] for each component c:

\n\n\n\n

What is this doing? Suppose you knew that you had a time to failure of j, but you added a component with a time to failure of k. Regardless of what components you had before, your new time to fail is LCM(j, k). This follows from the fact that for two sets A and B, LCM(A union B} = LCM(LCM(A), LCM(B)).

\n\n

Similarly, if we're considering a time to failure of T(i) and our new component's time to failure of T(c), the resultant time to failure is LCM(T(i), T(c)). Note that we recorded this time to failure for dp[i][n-1] configurations, so we should record that many new times to failure once the new component is introduced.

\n\n

Why do the big primes not contribute to the number of states?

\n\n
\n

Each of them occurs either 0 or 1 times. Should the number of states not be multiplied by 2 for each of these primes (leading to a non-feasible state space again)?

\n
\n\n

You're right, of course. However, the solution sketch states that numbers with large primes are handled in another (unspecified) fashion.

\n\n

What would happen if we did include them? The number of states we would need to represent would explode into an impractical number. Hence the author accounts for such numbers differently. Note that if a number less than or equal to 500 includes a prime larger than 19 the other factors multiply to 21 or less. This makes such numbers amenable for brute forcing, no tables necessary.

Given: set A = {a0, a1, ..., aN-1} (1 ≤ N ≤ 100), with 2 ≤ ai ≤ 500.

\n\n

Asked: Find the sum of all least common multiples (LCM) of all subsets of A of size at least 2.

\n\n

The LCM of a setB = {b0, b1, ..., bk-1} is defined as the minimum integer Bmin such that bi | Bmin, for all 0 ≤ i < k.

Example:

Let N = 3 and A = {2, 6, 7}, then:

The problem is obtained from a competition*, which also provided a solution sketch. This is where my problem comes in: I do not understand the hinted approach.

The solution reads (modulo some small fixed grammar issues):

The solution is a bit tricky. If we observe carefully we see that the integers are between 2 and 500. So, if we prime factorize the numbers, we get the following maximum powers:

So how to enable selecting rows in GridView?

I agree with Jonathan Lin

\n\n

But if the fragment you want to update is the fragment that is currently shown you can do something similar to this:

\n\n
public class DisplayPagerAdapter extends FragmentPagerAdapter {\n\nprivate static final String TAG = \"DisplayPagerAdapter\";\n\nSparseArray<DisplayFragment> registeredFragments = new SparseArray<DisplayFragment>();\n\npublic DisplayPagerAdapter(FragmentManager fm) {\n    super(fm);\n}\n\n@Override\npublic int getCount() {\n    DisplayCoreModule display = DisplayCoreModule.getInstance();\n    return (display != null && display.getPagesCount() > 0) ? display.getPagesCount() : 1;\n}\n\n@Override\npublic int getItemPosition(Object object) {\n    return POSITION_NONE;\n}\n\n\n@Override\npublic Fragment getItem(int position) {\n    Log.d(TAG, \"getItem \" + position);\n    return DisplayFragment.newInstance(position); \n}\n\n@Override\npublic CharSequence getPageTitle(int position) {\n    DisplayCoreModule display = DisplayCoreModule.getInstance();\n    if (display != null && display.getPagesCount() > 0) {\n        return \"Side \" + (position+1);\n    } else {\n        return super.getPageTitle(position);\n    }\n}\n\n@Override\npublic Object instantiateItem(ViewGroup container, int position) {\n    Log.d(TAG, \"instantiateItem \" + position);\n    DisplayFragment fragment = (DisplayFragment) super.instantiateItem(container, position);\n    registeredFragments.put(position, fragment);\n    return fragment;\n}\n\n@Override\npublic void destroyItem(ViewGroup container, int position, Object object) {\n    Log.d(TAG, \"destroyItem \" + position);\n    registeredFragments.remove(position);\n    super.destroyItem(container, position, object);\n}\n\npublic Fragment getRegisteredFragment(int position) {\n    return registeredFragments.get(position);\n}\n\npublic SparseArray<DisplayFragment> getRegisteredFragments() {\n    return registeredFragments;\n}\n\n}\n
\n\n

It is the registeredFragments part that I wanted to show you.

\n\n

Since you use FragmentPagerAdapter then getRegisteredFragment(int position) will always return one of your fragments given that you provide a valid position. Should you change to FragmentStatePagerAdapter at some point, it can return null on some of the positions.

\n\n

Now, in TrackFragment create a callback to your MainActivity, which then informs LogFragment, shown here in pseudo code:

\n\n
Fragment TrackFragment  {\n\n    interface TrackFragmentCallback() {\n        public void newInfo()\n    }\n\n    TrackFragmentCallback trackFragmentCallback;\n\n    onAttatch() {\n        // make sure to implement TrackFragmentCallback on MainActivity \n        trackFragmentCallback = (TrackFragmentCallback)getActivity();\n    } \n\n    // When this fragment has new info, simply do:\n    trackFragmentCallback.newInfo();\n}\n\nMainActivity implements TrackFragmentCallback {\n\n    newInfo() {\n        // get LogFragment\n        LogFragment logFragment = pagerAdapter.getRegisteredFragment(1); \n        if (logFragment != null) {\n            logFragment.update();\n        }\n    }\n}\n
\n\n

Hope this helps.

I dont know how to refresh a fragment or reload it when it's \"active\" again.

\n\n

TabsPagerAdapter.java:

\n\n
public class TabsPagerAdapter extends FragmentPagerAdapter{\n\n\n    public TabsPagerAdapter(FragmentManager fm){\n        super(fm);\n    }\n\n    @Override\n    public Fragment getItem(int index) {\n\n        switch (index) {\n        case 0:\n\n            return new KFZFragment();\n        case 1:\n\n            return new LogFragment();\n        case 2:\n\n            return new TrackFragment();\n        }\n\n        return null;\n    }\n\n    @Override\n    public int getCount() {\n        // get item count - equal to number of tabs\n        return 3;\n    }\n\n}\n
\n\n

I have this 3 Fragments (KFZFragment,LogFragment,TrackFragment) and on the TrackFragment I calculate some data and this data should be display in a ListView in LogFragment.\nBut when I change to LogFragment it's not the latest data. So it doesnt refresh.

I need to start a telephone call and I am using this code (that works perfectly):

\n\n
NSString *phoneCallNum = [NSString stringWithFormat:@\"tel://%@\",phoneNumber];\n\n[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneCallNum]];\n
\n\n

But I need to check if the call was connected or simply the call ended without connect.

\n\n

I found that Core Telephony notifies this using something like:

\n\n
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(callConnected:) name:CTCallStateConnected\n                                           object:[UIApplication sharedApplication]];\n\n[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(callEnded:) name:CTCallStateDisconnected object:[UIApplication sharedApplication]];\n
\n\n

So how can I link both? I tried this code:

\n\n
- (void)callNumber:(CDVInvokedUrlCommand*)command\n{\n   CDVPluginResult* pluginResult = nil;\n   NSString* phoneNumber = [command.arguments objectAtIndex:0];\n\n   self.callbackID = command.callbackId;\n\n   [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(callConnected:) name:CTCallStateConnected\n                                           object:[UIApplication sharedApplication]];\n\n   [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(callEnded:) name:CTCallStateDisconnected object:[UIApplication sharedApplication]];\n\n   NSString *phoneCallNum = [NSString stringWithFormat:@\"tel://%@\",phoneNumber];\n\n   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneCallNum]];\n\n   NSLog(@\"phone btn touch %@\", phoneCallNum);\n}\n\n- (void) callConnected: (NSNotification *)notification\n{\n   BOOL succeeded = YES;\n   NSLog(@\"Call connected\");\n}\n

I'm trying to use maven to auto generate pojo for my postgres database. Though even if I take maven out of the equation I have the issue.

\n\n

My data is split upon multiple schemas, and I'll need to work with all of them in my code base. I'd like to know how I can accomplish this short of setting up a task for each one of them in maven. This is what I have so far.

\n\n

Obviously this only seems to work for a single schema. I'd like to be able to generate POJOs for multiple ones. I tried multiple xml elements, or comma delimited but it just errors out.

It seems that the general recommendation is to use do so like in this SO question:

However, my code does not compile when I reference the RootDirectory property. The error I see is below

Now, the weird part is that while debugging, I am able to evaluate the RootDirectory property correctly in the Quick Debug window.

Am I missing something obvious? Like I said, I'm completely new to SharePoint.

My feature is scoped to the Web level, and I do have a reference to Microsoft.Sharepoint.Administration in my using statements.

I am trying to make a tictactoe project in jQuery and I am having a major problem...

\n\n

The tiles are in <td> tags and I am trying to make it so that when the user clicks the the tile, it calls the \"marked\" function.

\n\n

If we now look into the \"marked\" function, $(this) is intended to be the <td> node that the function was called from.

\n\n

However, it wasn't doing anything so I checked the console and apparently $(this) was containing the DOM Window object.

\n\n

Is there anyway I can send the right kind of $(this) to the \"marked\" function?

\n\n

Thank you!

I am using paypal rest API for recurrent billing.

\n\n

Is there any way to predict date for next payment for billing agreement?

\n\n

When I create & execute agreement, paypal will provide me this info:

\n\n
\"start_date\": \"2014-10-26T07:00:00Z\",\n\"cycles_remaining\": \"1\",\n\"cycles_completed\": \"0\",\n\"next_billing_date\": \"2014-10-26T10:00:00Z\",\n\"final_payment_date\": \"1970-01-01T00:00:00Z\",\n\"failed_payment_count\": \"0\"\n
\n\n

When I check transactions after next_billing_date, there is no payment. However, after a longer time a payment arrive and when I retrieve the same agreement, I get this:

\n\n
\"start_date\": \"2014-10-26T07:00:00Z\",\n\"agreement_details\": {\n    \"outstanding_balance\": {\n        \"currency\": \"USD\",\n        \"value\": \"0.00\"\n    },\n    \"cycles_remaining\": \"0\",\n    \"cycles_completed\": \"0\",\n    \"next_billing_date\": \"2014-11-26T10:00:00Z\",\n    \"last_payment_date\": \"2014-10-28T05:00:55Z\",\n    \"last_payment_amount\": {\n        \"currency\": \"USD\",\n        \"value\": \"0.01\"\n    },\n    \"final_payment_date\": \"1970-01-01T00:00:00Z\",\n    \"failed_payment_count\": \"0\"\n
\n\n

So the payment was made 1d 19h after the date provided in agreement.

\n\n

If those 'delays' will be max 3 days, it will be OK. But I need to be sure.

I'm lost on what I'm doing wrong, and I can't see anyone else with this problem, so it's gotta be me.

\n\n

I've just setup Indatus\\Dispatcher\\ServiceProvider and have everything running just fine. For testing purposes, I'm just running a single scheduled event every 5 minutes to add a log entry.

\n\n

For some reason, it's duplicating the log entries.

\n\n

Here's what the output is looking like:

\n\n
[2014-10-26 19:00:15] local.INFO: This is a test [] []\n[2014-10-26 19:00:15] local.INFO: This is a test [] []\n[2014-10-26 19:05:12] local.INFO: This is a test [] []\n[2014-10-26 19:05:13] local.INFO: This is a test [] []\n[2014-10-26 19:10:09] local.INFO: This is a test [] []\n[2014-10-26 19:10:10] local.INFO: This is a test [] []\n
\n\n

Here's the actual scheduled fire() event:

\n\n
public function fire()\n{\n    Log::info('This is a test');\n}\n
\n\n

The schedule() :

\n\n
public function schedule(Schedulable $scheduler)\n{\n    return $scheduler->everyMinutes(5);\n\n}\n
\n\n

and I've checked the scheduled:summary and it's only showing once:

\n\n
+----------------+------------------+-----------+--------+------+--------------+-------+-------------+--------+\n| Environment(s) | Name             | Args/Opts | Minute | Hour | Day of Month | Month | Day of Week | Run as |\n+----------------+------------------+-----------+--------+------+--------------+-------+-------------+--------+\n| *              | schedule:test    |           | */5    | *    | *            | *     | *           |        |\n+----------------+------------------+-----------+--------+------+--------------+-------+-------------+--------+\n
\n\n

And finally my crontab entry, which is only listed in the file once:

\n\n
* * * * * php /vagrant/myapp/artisan scheduled:run 1>> /dev/null 2>&1\n
\n\n

I can't see any duplication that would cause it to run twice.

\n\n

Any ideas what I've got wrong?

Basically you want to know

\n\n\n\n

If you push the errors into a list, the results will be ready at the end (order not guaranteed of course).

\n\n

For the second part, if you keep an array of the ajax promises returned from each $.ajax you can use $.when and wait for them all to complete using always().

\n\n

As a basic example (other details removed):

\n\n
var listing = {}; // data from reddit API\nvar promises = [];\nvar results = [];\n$.each(listing, function(key, value) {\n    // [snip]\n    promises.push($.ajax({\n            type: \"HEAD\",\n            url: \"https://gdata.youtube.com/feeds/api/videos/\" + videoID,\n            error: function() { \n                //[snip]\n                results.push({\n                   itemArtist: itemArtist,\n                   videoID: videoID,\n                   url: itemURL});\n            }\n        });\n    );\n}\n// Wait for all promises to complete (pass or fail) \n$.when.apply($, promises).always(function(){\n    // process list of failed URLs\n});\n
\n\n

Apologies for any typos. This was coded straight into the answer, but you get the idea.

\n\n

I note you mention 100s of requests, but the browser will only allow a handful through at a time, so no need for additional processing.

\n\n

If always is not working you can add your own deferred objects that resolve on success or fail:

\n\n

I'm having trouble with some dumb architecture because I'm dumb. I'm trying to loop over YouTube videos posted to Reddit, extract URLs and process them into an .m3u playlist.

\n\n

Full code at Subreddit to YouTube Source Bookmarklet - Play YouTube music from subreddits in Foobar with foo_youtube

\n\n

At some point I get the idea that I could check each URL to see if the video is dead or not, and offer an alternative if they're removed.

\n\n

So I do AJAX requests to YouTube API and if there's an error I'm supposed to react to it and change that item's URL.

\n\n

But the problem is it only works if the AJAX is NOT async - this takes many seconds, during which the page is jammed.

\n\n

I'd like to let the AJAX be async but I don't know how I should structure my code.

\n\n

Here is PSEUDOCODE of how it is now:

I have a major gap in operating ng routing functionalists.\nHere is what I want to achieve: I have a main page which directs to dashboard.html and another \nbuildings.html. \nThe buildings page could be called with many parameters, such as: id, type, color\nSo a traditional url would look like that:

\n\n
/buildings?id=110&type=special&color=red\n
\n\n

So as far as I understand in angular ngroute I should have this structure:

\n\n
$routeProvider\n\n            // route for the main page which will direct to the buildings page\n            .when('/', {\n                templateUrl : 'web/pages/dashboard.html',\n                controller  : 'dashboardController',\n                controllerAs : 'dashboard'\n            })\n\n            // route for the main page which will direct to the buildings page\n            .when('/buildings/:buildingId/:buildingType/:buildingColor', {\n                templateUrl : 'web/pages/buildings.html',\n                controller  : 'mainController',\n                controllerAs : 'buildings'\n            })\n            ;\n\n}); \n
\n\n

And the url should be like:

\n\n
/buildings/110/special/red\n
\n\n

What I don't get is how to call for the buildings page with only id or with type and color?\nAnd if I have 7 parameters and want to trigger a call with only 3, how should I do that?

\n\n

I'm using $location.path to shift between pages when needed based on gui events, for example:\n$location.path( '/buildings/'+$scope.id);

\n\n

Thanks.

Here are Process Monitor logs captured during Visual Studio Debugging HTTP (not working) and HTTPS (working)

\n\n

(Test performed on random MVC Tutorial)

\n\n

Use CTRL+F and Look for \"Visual Studio Web Debugger.log\" in logs to get the idea when it is happening. In https log is good, in http log returns Invalid Verb error mentioned before.

\n\n\n\n

I might be wrong, but I think the key here is that only HTTP doesn't work and only with VS Debugger, everything else is just fine.
