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 each input has exactly one solution, and you may not use the same element twice. You can return the answer in any order.
nums = [array of integers], target = integer
int[] (two indices)
Example 1:
Input:
nums = [2,7,11,15] target = 9
Output:
[0,1]
Explanation:
nums[0] + nums[1] = 2 + 7 = 9, so return [0, 1].
Example 2:
Input:
nums = [3,2,4] target = 6
Output:
[1,2]
Explanation:
nums[1] + nums[2] = 2 + 4 = 6.
