总结:不敢爱你么开口 package com.sads; ///实现随机输出100个数字,数字是0到9之间,每行输出10个 public class Wss { public static void main(String[] args) { int a[] = new int[100]; for (int i = 0; i < 100; i++) { a[i] = (int) (Math.random() * 10); } for (int i = 0; i < 100; i++) { if
一道非常经典的C#笔试题: 需求:请使用C#将一个长度为100的int数组,插入1-100的随机数,不能重复,要求遍历次数最少. 1.最简单的办法 var rd = new Random(); List<int> list = new List<int>(); ; ) { num = rd.Next(, ); if (!list.Contains(num)) { list.Add(num); } } 这种办法无需解释. 2.进阶 var rd = new Random(); var
