给定一个整数数组 nums 和一个目标值 target,请你在该数组中找出和为目标值的那 两个 整数,并返回他们的数组下标。
你可以假设每种输入只会对应一个答案。但是,数组中同一个元素不能使用两遍。
示例:
给定 nums = [2, 7, 11, 15], target = 9 因为 nums[0] + nums[1] = 2 + 7 = 9 所以返回 [0, 1]

/** * @param {number[]} nums * @param {number} target * @return {number[]} */ var twoSum = function(nums, target) { let map=new Map(),loop=0; while(loop<nums.length){ let item=nums[loop] let index=target-item; let flag=map.has(index) if(flag){ return [map.get(index),loop] } map.set(item,loop) loop++ } };
Sorry, something went wrong.
