Question 167. Two Sum II - Input array is sorted Solution 题目大意:和Two Sum一样,这里给出的数组是有序的 思路:target - nums[i],这样就实现了降维了 Java实现: public int[] twoSum(int[] nums, int target) { int[] result = new int[2]; Map<Integer, Integer> map = new HashMap<>(); f…

1.two sum 用hash来存储数值和对应的位置索引,通过target-当前值来获得需要的值,然后再hash中寻找 错误代码1: Input:[3,2,4]6Output:[0,0]Expected:[1,2] 同一个数字不能重复使用,但这个代码没排除这个问题 class Solution { public: vector<int> twoSum(vector<int>& nums, int target) { vector<int> result; uno…

这是悦乐书的第179次更新,第181篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第38题(顺位题号是167).给定已按升序排序的整数数组,找到两个数字,使它们相加到特定的目标数.函数twoSum应该返回两个数字的索引,使它们加起来到目标,其中index1必须小于index2. 注意: 返回的答案(index1和index2)不是从零开始的. 可以假设每个输入只有一个解决方案,并且您可能不会两次使用相同的元素. 例如: 输入:数字= [2,7,11,15],目标=…
