这个是LeetCode鼻祖 两数之和 题目的升级版本,不过难度也只是略有提升。做法和之前的 Two Sum 差别不大。 回顾下两数之和 题目1(Two Sum): 问题描述:给定一个整数数组 nums 和一个目标值 target,请你在该数组中找出和为目标值的那两个整数,并返回它们的数组下标。 条件:数组未排序,每种输入只会对应一个答案,不能使用同一个元素两次
Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Note: Your...

对于一些了解HashMap这种数据结构的同学,很容易能想到利用HashMap来求解,也就是和LeetCode第一题TwoSum相同的解法 classSolution{publicint[]twoSum(int[]numbers,inttarget){Map<Integer,Integer>map=newHashMap<>();for(inti=0;i<numbers.length;i++){// map.put(numbers[i], i); //如果放在这里可能会...
每天一算:Two Sum II leetcode上167号问题:Two Sum II 给定一个已按照升序排列 的有序数组,找到两个数使得它们相加之和等于目标数。 函数应该返回这两个下标值 index1 和 index2,其中 index1 必须小于 index2。 说明: 返回的下标值(index1 和 index2)不是从零开始的。
