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 1:
nums = [2,7,11,15], target = 9[0,1]Because nums[0] + nums[1] == 9, we return [0, 1].
Example 2:
nums = [3,2,4], target = 6[1,2]$ Run your code to see output here...
