［抄题］: Shuffle a set of numbers without duplicates. Example: // Init an array with set 1, 2, and 3. int[] nums = {1,2,3}; Solution solution = new Solution(nums); // Shuffle the array [1,2,3] and return its result. Any permutation of [1,2,3] must equal…

数组洗牌,最近直接的想法是从数组随机取出一个元素,放到另一个数组中,但是这样取出的元素会有重复,必须采取一定的方法保证: 1. 元素不能重复2. 元素被抽取的概率相等,即随机性 数组洗牌经典算法有两种: 1. Fisher-Yates Shuffle(复杂度(n^2)) 数组的删除以及新的copy数组都是耗费时间和空间的. javascript实现 function FyShuffle(arr){ var copy = [], len = arr.length, n; while(len) n…

Given a sorted positive integer array nums and an integer n, add/patch elements to the array such that any number in range [1, n] inclusive can be formed by the sum of some elements in the array. Return the minimum number of patches required. Example…

给定两个大小相等的数组 A 和 B,A 相对于 B 的优势可以用满足 A[i] > B[i] 的索引 i 的数目来描述. 返回 A 的任意排列,使其相对于 B 的优势最大化. 示例 1: 输入:A = [2,7,11,15], B = [1,10,4,11] 输出:[2,11,7,15] 示例 2: 输入:A = [12,24,8,32], B = [13,25,32,11] 输出:[24,32,8,12] 思路:把A的全排列的各种情况都考虑一下,找到最多的优势,然后将该排列输出,代码如下 ve…
