Problem

Problem

Given an integer array nums and an integer target, return the indices of the two distinct elements whose sum equals target. Return the answer as a list of two indices in any order. You may assume exactly one valid pair exists, and the same element cannot be used twice.

Constraints

2 <= len(nums) <= 10^4
-10^9 <= nums[i] <= 10^9
-10^9 <= target <= 10^9
Exactly one valid answer exists
