主要是打乱的算法:arc4random_uniform但是leetCode一直报未定义,所以就直接使用Swift 4.2+ 的内置方法了。。。可以参考下面这个Stack Overflowd的回答 How do I shuffle an array in Swift? 代码: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 class Solution { var num: [Int] init(_ nums: [Int])...
LeetCode初级 一、引子 这是由LeetCode官方推出的的经典面试题目清单~ 这个模块对应的是探索的初级算法~旨在帮助入门算法。我们第一遍刷的是leetcode推荐的题目。 二、题目 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。
题目地址:https://leetcode-cn.com/problems/shuffle-the-array/ 题目描述 给你一个数组nums,数组中有2n个元素,按[x1,x2,...,xn,y1,y2,...,yn]的格式排列。 请你将数组按[x1,y1,x2,y2,...,xn,yn]格式重新排列,返回重排后的数组。

之前做 find K largest number in array 正好做过类似的。 这道题目不是很好。很难检查。 reference: https://discuss.leetcode.com/topic/53985/well-explained-o-n-java-solution-by-using-random-class-and-swapping-current-with-a-random-previous-index ...
