* @brief Two Sum
*
* 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.
*
* @param nums the array of integers to be summed
* @param target the target integer
