Given an array of integers `nums` and an integer `target`, return the *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.
Examples & Test Cases
Example 1:
Input: 2 7 11 15
9
Output: 0 1
Explanation: Because nums[0] + nums[1] == 9, we return 0 1.
Example 2:
Input: 3 2 4
6
Output: 1 2
Explanation: Because nums[1] + nums[2] == 6, we return 1 2.
