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...
Given an array of integers that is alreadysorted 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 ...
LeetCode167. Two Sum II - Input array is sorted(双指针) 题意:对于一个有序数组,输出和为target的两个元素的下标。题目保证仅有唯一解。分析:法一:二分。枚举第一个元素,二分找另一个元素,时间复杂度O(nlogn),非最优解。1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22...

167.two-sum-ii-input-array-is-sorted 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。
if (temp == target)先判断与目标数是否相同 可减少运行时间(因为Leetcode是拿很多不同数据来运行,而不是一条超长数据。仔细想想这里的区别) temp=numbers[i] + numbers[j]先把两数之和记录下来,像py3里那种判断两次(==、>)每次都计算一次两数和,会消耗更多时间,这在判断条件增多时会很明显。
The tests are generated such that there isexactly one solution. Youmay notuse the same element twice. Your solution must use only constant extra space. Example 1: Input:numbers = [2,7,11,15], target = 9 Output:[1,2] Explanation:The sum of 2 and 7 is 9. Therefore, index1 = 1, ...
