Problem

Given an integer array nums and an integer target, return the indices of the two distinct elements whose sum equals target. Assume exactly one valid pair exists.

Examples

Example 1

Inputnums = [2, 7, 11, 15], target = 9Output[0, 1]Why2 + 7 = 9

Example 2

Inputnums = [3, 2, 4], target = 6Output[1, 2]Why2 + 4 = 6

Constraints

`2 <= len(nums) <= 10^5`
`-10^9 <= nums[i] <= 10^9`
`-10^9 <= target <= 10^9`
Exactly one valid answer exists
