Given an array of integers, return the 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 1:
Input: nums = [2,7,11,15], target = 9
Output: [0,1]Example 2:
Input: nums = [3,2,4], target = 6
Output: [1,2]Constraints:
- 2 <= nums.length <= 10^4
- -10^9 <= nums[i] <= 10^9
- -10^9 <= target <= 10^9
- Only one valid answer exists, and the same element cannot be used twice.
