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…
