Coding Interview questions set 6

Let's begin with set 6, 13)Given an array of integer nums and an integer target, return indices of the two numbers such that they add up to the target. Assumptions: Each input would have exactly one solution, and you may not use the same element twice. Example 1: Input: nums = [2,7,11,15], target = 9 Output: [0,1] Output: Because nums[0] + nums[1] == 9, we return [0, 1]. Example 2: Input: nums = [3,2,4], target = 6 Output: [1,2] Solution: const twoSum = (nums, target) => { const map = {}; for (let i = 0; i < nums.length; i++) { const another = target - nums[i]; if (another in map) { return [map[another], i]; } map[nums[i]] = i; } return null; }; You may also like these articles: Coding Interview Set 1 Coding Interview Set 2 .
