Two Sum

EasyArray/Hashing

AmazonGoogle

Given an array of integers nums and an integer target, return indices of the two numbers that add up to target. You may assume that each input has exactly one solution, and you may not use the same element twice.

Examples

Input: nums = [2,7,11,15], target = 9

Output: [0,1]

Because nums[0] + nums[1] == 9, we return [0, 1].

Input: nums = [3,2,4], target = 6

Output: [1,2]

Constraints

2 <= nums.length <= 10^4
-10^9 <= nums[i] <= 10^9
-10^9 <= target <= 10^9
