Discription
/**
* Given an array of integers, return indices of the two numbers such that they add up to a specific target.
*
* You may assume that each input would have exactly one solution, and you may not use the same element twice.
*
* Example:
*
* Given nums = [2, 7, 11, 15], target = 9,
*
* Because nums[0] + nums[1] = 2 + 7 = 9,
* return [0, 1].
