384. Shuffle an Array c++ random函数:https://www.jb51.net/article/124108.htm rand()不需要参数,它会返回一个从0到最大随机数的任意整数,最大随机数的大小通常是固定的一个大整数. 这样,如果你要产生0~10的10个整数,可以表达为: int N = rand() % 11; 这样,N的值就是一个0~10的随机数,如果要产生1~10,则是这样: 总结来说,可以表示为: a + rand() % n 其中的a是起始值,n是整…

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 equally lik…

打乱一个没有重复元素的数组.示例:// 以数字集合 1, 2 和 3 初始化数组.int[] nums = {1,2,3};Solution solution = new Solution(nums);// 打乱数组 [1,2,3] 并返回结果.任何 [1,2,3]的排列返回的概率应该相同.solution.shuffle();// 重设数组到它的初始状态[1,2,3].solution.reset(); 详见:https://leetcode.com/problems/shuffle-an-a…

题目: Shuffle a set of numbers without duplicates. 分析: 对一组不包含重复元素的数组进行随机重排,reset方法返回最原始的数组,shuffle方法随机返回数组的一个排列, 并且使得获得数组每一个排列的概率都是相同的.为此,可以在初始化时,求出数组的所有排列.在使用shuffle方法时,随机返回全排列中的一个. 代码: public class Solution { //存储数组的所有排列 List<int[]> list = new Array…
