Two Sum with Hash Map | Dataford Interview Questions

Given an array of integers nums and an integer target, return the indices of the two distinct elements whose values add up to target. Return the answer as a list of two indices in any order. You may assume exactly one valid pair exists.

Constraints

2 <= len(nums) <= 10^5
-10^9 <= nums[i] <= 10^9
-10^9 <= target <= 10^9
Exactly one valid answer exists
You may not use the same element twice

Function Signature
