Don’t try to use dynamically named variables. That’s simply not how variables work in C#. Use an array of lists: List<string>[] user = new List<string>[infoForUserSessions.Count]; for (int i = 0; i < infoForUserSessions.Count; i++) { user[i] = new List<string>(); } If the number of sessions can change, you would use a List<List<string>> instead, so that … Read more
The following is related to the JSON.simple library. You need a JSONParser instance to get a JSONObject value from your String object. JSONObject data; try { JSONParser helper = new JSONParser(); data = (JSONObject)helper.parse(String); } catch (ParseException parse) { // Invalid syntax return; } // Note that these may throw several exceptions JSONObject node = … Read more
TL;DR *p equals c Explanation Hi, first take a look at how to format a question on stack overflow. You should write your code directly in the question. So your question is about the understanding of these lines: char c,*p; p = &c *p = ‘Z’ printf(“%c”, c) // ‘Z’ First you’re declaring two different … Read more
Currently gRPC is described as to be a way for wcf migration, you can communicate in half streaming, full streaming. But be careful that half streaming can interrupt to collect information but it will not interrupt all the process on the server side. From what i seen, on asp.net (there is a core version) the … Read more
I don’t know your codes, because you provided none. So I’ll try to guess. It seems like you do not say to your client he will download an image. Try adding this to your response header : Content-type: image/jpeg I’ll give some example code, but I can’t promise it will work for you. @GetMapping(path = … Read more

You can use APPLY : SELECT t.ID, MIN(t.startdate) AS StartDate, MAX(t.Enddate) AS EndDate FROM table t OUTER APPLY ( SELECT TOP (1) t1.Enddate FROM table t1 WHERE t1.id = t.id AND t1.startdate >= t.startdate AND t1.enddate IS NOT NULL ORDER BY t1.startdate ) t1 GROUP BY t.ID, t1.Enddate; solved SELECT Record that have start date … Read more
you can use ‘GestureDetector’ instead of ACTION_DOWN. Example, GestureDetector gestureDetector = new GestureDetector(this, new GestureDetector.SimpleOnGestureListener() { @Override public boolean onSingleTapUp(MotionEvent e) { //——————apply your logic here———— return super.onSingleTapUp(e); } @Override public boolean onSingleTapConfirmed(MotionEvent e) { return super.onSingleTapConfirmed(e); } }); and pass touch event to gesture. @Override public boolean onTouchEvent(MotionEvent event) { gestureDetector.onTouchEvent(event); return super.onTouchEvent(event); } … Read more
If you want to measure the elapsed time to execute a funcV1 in seconds: ` import time start=time.time() print(funcV1(sample,result)) finish= time.time() print(“elapsed time=”,finish-start) ` solved What does e-0 mean in Python? [duplicate]
I changed 2 things : while n > 1: instead of while n > 0: otherwise your loop never stops n=n//10 instead of n=n/10, where // is the euclidian division, which is what you need here You should try this : def testD(D,n): if D % 2 == 0: return 0 count = 0 while … Read more

No,this is not agile practices.When a programmer is doing the mentioned changes ,it means he/she is not well prepared to the project work. Agile allows to work in collaboration where each member of the team help one another in a problem so that the final code produced will result in less change, and will be … Read more
Use array_diff and array_merge: $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); Here’s a demo. For multiple arrays, combine it with a callback and array_reduce: function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array(‘green’, ‘red’, ‘blue’), array(‘green’, ‘yellow’, ‘red’) ); $result = array_reduce($arrays, ‘unique’); And here’s a demo … Read more
The time difference (in milliseconds) can be obtained using: ChronoUnit.MILLIS .between(Instant.parse(“2018-07-26T16:00:17.163Z”), Instant.now()) Instant.now() will be the current UTC time, and your input date is UTC time, which makes the diff sensible. Regardless of the current time zone, the difference will be consistent. You can change the time unit accordingly (such as ChronoUnit.HOURS). 0 solved How … Read more
You can generate variable names in for loops like this. Just change the value of $how_many_i_want. $how_many_i_want = 3; for($x=0;$x<$how_many_i_want;$x++){ generate_entropy($x); } function generate_entropy($nth){ $kriteria = [‘C1′,’C2′,’C3′,’C4′,’C5′,’C6’]; $alternatif = [‘ALT1′,’ALT2′,’ALT’,’ALT4′,’ALT5′,’ALT6′,’ALT7′]; ${“nEntropy$nth”} = array(); for ($i=0;$i<count($kriteria);$i++){ for ($j=0;$j<count($alternatif);$j++){ ${“nEntropy$nth”}[$i] = (((-1)/log(7)) *( ($probabilitas[0][$nth]*log($probabilitas[0][$nth]))+ ($probabilitas[1][$nth]*log($probabilitas[1][$nth]))+ ($probabilitas[2][$nth]*log($probabilitas[2][$nth]))+ ($probabilitas[3][$nth]*log($probabilitas[3][$nth]))+ ($probabilitas[4][$nth]*log($probabilitas[4][$nth]))+ ($probabilitas[5][$nth]*log($probabilitas[5][$nth]))+ ($probabilitas[6][$nth]*log($probabilitas[6][$nth])) )); } } showb(${“nEntropy$nth”}); } 6 solved … Read more
