java - Riemann hypothesis prime number theorem -


so working on riemann hypothesis prime number theorem,
loop in method isprimenumber , loop okay because tested on separate class , worked well.. primes text area. problem here wanted info appended in text area once enter number in field, want when input 100, gives me primes numbers 1-99, giving me numbers 10,000 - prime numbers. appreciated. working well.. tried debugging couldn't locate problem, still learning more on debugging.

public void run() {         int quantity = integer.parseint(field.gettext());         int primenumbers = 0;         int allnumbers = 2;         primes.append("this prime numbers in " + quantity + " riemann hypothesis ");         while(primenumbers<quantity){             if(isprimenumber(allnumbers)){                 primes.append(allnumbers + " ");                 primenumbers++;             }             allnumbers++;         }

you're algorithm giving first 100 prime numbers (which run 541, not 10000). if want prime numbers 1 100 instead, change

while(primenumbers<quantity){

to

while(allnumbers<quantity){

angularjs - ADAL JS Angular- WebAPI add a new role claim to the token -

i have created angular spa webapi backend using adal js authentication.as there no roles in ad, need manually add role claims in order give users access different api controllers. the roles stored in database. expecting inject claim through call webapi after authentication ad. webapi code might this. identity.addclaim(new claim("role", "user")); var ticket = new authenticationticket(identity, props); var accesstoken = startup.oauthbeareroptions.accesstokenformat.protect(ticket); is possible replace adal idtoken new token? is viable solution or there other better way handle this? as initial token generated azuread, possible edit token add new claim? appreciated. graph api supporting group claims. see here: http://justazure.com/azure-active-directory-part-4-group-claims/ if @ examples on page, users assigned groups , app can check group in claims. in current version of portal, need app manifest , modify it.

i problem when make request (i can request). $link = 'http://uri/path/?param1=1&sid=2&sid=3&sid=4' $http = $httpsocket = new httpsocket(); $res = $httpsocket->get($link); if check request pr($http); i see : [line] => /url/path/?param1=1&sid%5b0%5d=2&sid%5b1%5d=3&sid%5b2%5d=4 http/1.1 and i'm getting empty response because server doesn't know parameters sid%5b0%5d=2 when try send parameters array : $data = array('param1' => '1', 'sid' => array('2','3', '4')); i see same changes %5b0%5d - additional indexes. how fix it? unfortunately , can not change server side, if send request in browser, i'll normal response in json format. when make request, can parameters this: $param1 = $_get['param1']; $sid= $_get['sid']; tip: use diferente names parameters. have multiples sid. use sid1, sid2, sid3... update: can parameters this:...
