// Two Sum — EASY

// Category: array

Given an array of integers `nums` and an integer `target`, return indices of the two numbers such that they add up to `target`.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

You can return the answer in any order.

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

Output: [0, 1]
