Two Sum Using Hash Map

EasyPython

Problem

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 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
The same element cannot be used twice

Function Signature
