Leetcode Solutions(一) two-sum Two Sum 题目 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数。 你可以假设每个输入只对应一种答案,且同样的元素不能被重复利用。 示例: 给定 nums = [2, 7, 11,…
LeetCode刷题Two Sum 🍀题目 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。但是,数组中同一个元素在答案里不能重复出现。
这个问题很经典,对于3Sum,先确定一个数字,然后这个问题就退化成了2Sum的问题。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 Su...
