return [0, 1]. 这道Two Sum 的题目作为 LeetCode 的开篇之题,乃是经典中的经典,正所谓‘平生不识 TwoSum,刷尽 LeetCode 也枉然’,就像英语单词书的第一个单词总是 Abandon 一样,很多没有毅力坚持的人就只能记住这一个单词,所以通常情况下单词书就前几页有翻动的痕迹,后面都是崭新如初,道理不需多讲,鸡汤...

3).我选择设置一个stopflag=0,遇到-4则stopflag=1 完成数值复原操作 得到:nums =[2,7,11,15] 和 target = 9 5.最后就是TwoSum函数的编写与调用,十分简单看代码即可明白 附上代码 函数部分 ` public class Solution { public int[] twoSum(int[] nums, int target) { int [] answer = new int[2...
