The problem "Two Sum" requires finding two numbers in aninteger arraysuch that their sum equals a specifiedtargetnumber. You need to returnthe indices ofthese two numbers, whereindices start from 0. The indices ofthe two numbers cannot be the same, and there isexactly one solutionfor each i...
[LeetCode] Two Sum, Solution 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 note that your...
这样我们创建一个哈希表,对于每一个 x,我们首先查询哈希表中是否存在 target - x,然后将 x 插入到哈希表中,即可保证不会让 x 和自己匹配。 class Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: hashtable = dict() for i, num in enumerate(nums): if target - num ...

2. 两数相加 - 给你两个 非空 的链表,表示两个非负的整数。它们每位数字都是按照 逆序 的方式存储的,并且每个节点只能存储 一位 数字。 请你将两个数相加,并以相同形式返回一个表示和的链表。 你可以假设除了数字 0 之外,这两个数都不会以 0 开头。 示例 1: [ht
1. 两数之和 - 给定一个整数数组 nums 和一个整数目标值 target,请你在该数组中找出 和为目标值 target 的那 两个 整数,并返回它们的数组下标。 你可以假设每种输入只会对应一个答案,并且你不能使用两次相同的元素。 你可以按任意顺序返回答案。 示例 1: 输入
