📚 今日挑战:LeetCode的Two Sum问题。给定一个整数数组和一个目标值,找出数组中和为目标值的两个整数,并返回它们的索引。💡 解题思路:首先,我们遍历数组,对于每个元素,计算目标值与当前元素的差值,并在剩余的数组中查找该差值是否出现。如果找到,则返回这两个元素的索引。💪 挑战自我:让我们一起通过LeetCode...

其它解法六:LeetCode 中国的普通解法,和解法二类似 class Solution: def twoSum(self, nums: List[int], target: int) -> List[int]: n = len(nums) for i in range(n): for j in range(i + 1, n): if nums[i] + nums[j] == target: return [i, j] return [] ## 找不到则返回空...
题目链接:https://oj.leetcode.com/problems/two-sum/ 问题: Given an array of integers, return indices of the two numbers such that they add up to a specific target.You may assume that each input would have exactly one solution. Example: Given nums = [2, 7, 11, 15], target = 9, ...
The function twoSum should return indices of the two numbers suchthat they add up to the target, where index1 must be less than index2.Please note that your returned answers (both index1 and index2) are notzero-based. You may assume that each input would have exactly one solution. Input...
针对2Sum,先对数组排序,然后使用双指针匹配可行解就可以解决,虽然可以考虑使用HashMap加速搜索,但是对于本题使用HashMap的与否的时间复杂度都一样,都是O(nlog(n))。可以参考这个链接: 求和问题总结(leetcode 2Sum, 3Sum, 4Sum, K Sum),写的很清楚。
