Kirat[ad_1] list.reverse operates in place. That means that it almost certainly does something like this under the hood: for i in range(len(self) // 2): j = len(self) – 1 – i self[i], self[j] = self[j], self[i] The actual method is implemented in C, so of course it will be much more verbose, especially in the … Read more
[ad_1] I’d say this is fine. The intent is different. Lets try this for example: String builder sb = new StringBuilder(); sb.append(“hello”).append(“hello”); sb.delete(0,5); sb.toString(); It prints “hello”. Had you read the documentation, you’d see that the end is non-inclusive, meaning it will delete from start to end-1, hence no IndexOutOfBounds. However, try this: StringBuilder builder … Read more

[ad_1] This is much easier with ES6 template literals: div.innerHTML = rawstr.split(“\n\n”).map(str => `<p>${str}</p>`)).join(“”); newstr = oldstr.split(/\s+“|”\s+/g).map(str => `”${str}”`)).join(” “); `${p[0]} (${p[1]}) ${p[2]}` 3 [ad_2] solved An elegant way to surround a string in Javascript [closed]
[ad_1] Very simple Use the str.split() function transform your alphabet soup, then split the single elements further by directly accessing them. For example: text=””‘ A1 A10 A10 B14 C1 C14 C14 C8 ”’ for t in text.split(): print( {t[0]: t[1:]} ) prints: {‘A’: ‘1’} {‘A’: ’10’} {‘A’: ’10’} {‘B’: ’14’} {‘C’: ‘1’} {‘C’: ’14’} {‘C’: … Read more
[ad_1] there are several issues in this code. first the closing of the controller brackets should be changed app.controller(“notePadCtrl”,function($scope){ $scope.message=””; $scope.left=function(){ return 100 – $scope.message.lenght; }; $scope.clear=function(){ $scope.message=””; }; $scope.save=function(){ alert(“file got saved”); }; }); then add the angular script tag inside the body or head tag <!DOCTYPE html> <html> <head> <script data-require=”[email protected]″ data-semver=”1.5.8″ src=”https://code.angularjs.org/1.5.8/angular.js”></script> … Read more

[ad_1] Java strings are immutable. Every time you do: s+=c; You’re really saying: s = new String(s + c); new String(s + c) must allocate a string of length s + 1, or: 1 2 3 4 5 6 7 8 9 … etc. Since Sum(1..N) == (n + 1) (n / 2), this is … Read more
[ad_1] Following is a naive method to achieve the desired functionality: Generate a mask of pixel indices with dummy values for pixel with zero value.
