javascript - unable to resolve access control issue -


this pretty known standard error unable fix same using existing stackoverflow posts.

xmlhttprequest cannot load https://myserver.com/context/
response preflight request doesn't pass access control check:
no 'access-control-allow-origin' header present on requested resource.
origin 'https://www.otherwebsite.com' therefore not allowed access.
response had http status code 405.

following code have -

function setheader(xhr) {     xhr.setrequestheader("access-control-allow-origin", "*"); }  var url = "https://myserver.com/context/"; $.ajax({     url: url,     type: 'get', datatype:'json',     success: function(data) {         _this.question(data.question);         _this.questionid(data.questionid);         _this.choices(data.choices);     }, error: function() {         console.log("error in getting microquestion");     },     beforesend: setheader });

the “response preflight request… had http status code 405.” message indicates, start, https://myserver.com/context/ endpoint needs configured handle options requests correctly—even if may set send right cors headers “normal” requests.

for details can read answer @ no 'access-control-allow-origin' header present on requested resource—when trying data rest api—but gist of is, minimally, server must respond options requests 2xx success status code.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
