Defined in header <functional> template < class T > struct less ; (until C++14) template < class T = void > struct less ; (since C++14) Function object for performing comparisons. Unless specialized, invokes operator< on type T . Specializations A specialization of std::less for any pointer type yields a strict total order, even if the built-in operator< does not. The strict total order is consistent among specializations of std::less , std::greater , std::less_equal , and std::greater_equal for that pointer type, and is also consistent with the partial order imposed by the corresponding built-in operators ( < , > , <= and >= ). If the function call operator of the specialization std::less<void> calls a built-in operator comparing pointers, it yields a strict total order even if the built-in operator< does not. This strict total order is consistent among the specializations std::less<v

BITree[0..n] --> Array that represents Binary Indexed Tree. arr[0..n-1] --> Input array for which prefix sum is evaluated. */ // Returns sum of arr[0..index].

Answer : Use builder: Picasso.Builder builder = new Picasso.Builder(this); builder.listener(new Picasso.Listener() { @Override public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) { exception.printStackTrace(); } }); builder.build().load(URL).into(imageView); Edit For version 2.71828 they have added the exception to the onError callback: Picasso.get() .load("yoururlhere") .into(imageView, new Callback() { @Override public void onSuccess() { } @Override public void onError(Exception e) { } }) When you use callback, the picaso will call method onSuccess and onError! File fileImage = new File(mPathImage); Picasso.with(mContext).load(fileImage) .placeholder(R.drawable.draw_detailed_view_display) .error

Answer : Javascript objects don't have a guaranteed inherent order, so there doesn't exist a "reverse" order. 4.3.3 Object An object is a member of the type Object. It is an unordered collection of properties each of which contains a primitive value, object, or function. A function stored in a property of an object is called a method. Browsers do seem to return the properties in the same order they were added to the object, but since this is not standard, you probably shouldn't rely on this behavior. A simple function that calls a function for each property in reverse order as that given by the browser's for..in, is this: // f is a function that has the obj as 'this' and the property name as first parameter function reverseForIn(obj, f) { var arr = []; for (var key in obj) { // add hasOwnPropertyCheck if needed arr.push(key); } for (var i=arr.length-1; i>=0; i--) { f.call(obj, arr[i]); } } //usage reverseFo

Answer : This window.addEventListener('keydown', keyDownListener, false) window is defined will all events in lib.d.ts and this particular listener as addEventListener(type: "keydown", listener: (ev: KeyboardEvent) => any, useCapture?: boolean): void; or this, if you want to keep your original "style", window.onkeydown = (ev: KeyboardEvent): any => { //do something }

Answer : In JavaScript, associative arrays are called objects. <script> var some_db = { "One" : "1", "Two" : "2", "Three" : "3" }; var copy_db = clone(some_db); alert(some_db["One"]); alert(copy_db["One"]); function clone(obj) { if (null == obj || "object" != typeof obj) return obj; var copy = obj.constructor(); for (var attr in obj) { if (obj.hasOwnProperty(attr)) copy[attr] = clone(obj[attr]); } return copy; } </script> I would normally use var copy_db = $.extend({}, some_db); if I was using jQuery. Fiddle Proof: http://jsfiddle.net/RNF5T/ Thanks @maja. As @Niko says in the comment, there aren't any associative arrays in JavaScript. You are actually setting properties on the array object, which is not a very good idea. You would be better off using an actual object. var some
