Two Sum

Implement twoSum

Given an array of integers nums and an integer target, return the indicesIndicesThe position of each element within the array, starting at 0 for the first element. 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. You can return the answer in any order.

Example 1:

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

Output: [0,1]

Example 2:

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

Output: [1,2]

Example 3:

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

Output: [0,1]

Constraints:

  • 2 ≤ nums.length ≤ 10⁴
  • -10⁹ ≤ nums[i] ≤ 10⁹
  • -10⁹ ≤ target ≤ 10⁹
  • Only one valid answer exists
