getRandomItem(arr)函数如下: var getRandomItem = function () { var preItem = null; return function (arr) { var index = Math.floor(Math.random() * arr.length), item = arr[index], result; arr = arr.sort(function() { // 数组随机排序(在这里...

This is sort of along the same lines as [previous]. It’s almost always a better idea to write code that is clean, straightforward, and legible than code that is as efficient as possible. The efficiency you think you are creating by doing things manually is more than likely a mirage. ...
cpp #include 然后,只需简单调用: cpp sort(起始地址, 结束地址); 这里的参数分别代表需要排序的数组或容器的起始和结束位置(结束位置不包含在内)。 三、升序与降序排序 升序排序(默认): cpp int arr[] = {5, 2, 9, 1, 5}; sort(arr, arr + 5); ...
基本语法排序的基本语法为: cpp sort(起始地址, 结束地址); 参数说明: 起始地址:要排序的数组或容器的开始位置。 结束地址:要排序的数组或容器的结束位置(不包含该地址)。 升序排序(默认方式) cpp int arr[] = {5, 2, 9, 1, 5}; sort(arr, arr + 5); // 排序后:1, 2, 5, 5, 9 ...
how to sort the values first ? O.o and for the other way i know that but cant do it as a code You grasp the principle but not the syntax of the language. There are still two levels in the syntax of the language. 1.To "use C++" you would exploit the standard library. For examp...
Of course you don't have to use those exact variable names, but that sort of thing. By the way, in my code I used these constants at the start: 1 2 constintROWS = 3;constintCOLS = 6; It is useful to use those for defining the size of arrays and setting loop conditions rather ...
