leetcode 【 Two Sum 】python 实现 题目: Given an array of integers, 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. Please not...
对于一个给定的数组,找出2个数,它们满足2个数的和等于一个特定的数,返回这两个数的索引。(从1开始) Given an array of integers, 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 tar...
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。
输入: numbers = [2, 7, 11, 15], target = 9 输出: [1,2] 解释:2与7之和等于目标数9。因此 index1 = 1, index2 =2。 Given an array of integers that is alreadysorted in ascending order, find two numbers such that they add up to a specific target number. ...

这道题是大名鼎鼎的LeetCode的第一题,也是面试当中非常常见的一道面试题。题目不难,但是对于初学者来说应该还是很有意思,也是一道很适合入门的算法题。 废话不多说,让我们一起来看看题目吧。 Given an array of integers, return indices of the two numbers such that they add up to a specific target. You...
Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target. You may assume that each input would have exactly one solution, and you may not use the same element twice. ...
