Two Sum

You're presented with an array of integers and a specific target value. Your task is to identify and return the indices of two numbers from the array that add up to the target. You can assume there's exactly one solution, and you can't use the same element twice. The indices can be returned in any order.

Input: nums = [14,8,22,6], target = 20

Output: [1,3]

Explanation: The integers at indices 1 and 3 (8 and 6) sum up to 20, so we return [1, 3].
