Two Sum - Challenge

Two Sum

Easy
Problem
Given an array of integers nums and an integer target, return the indices of the two numbers such that they add up to target.
Assume exactly one solution and you may not use the same element twice.
Constraints
  • 2 <= nums.length <= 10^4
  • -10^9 <= nums[i] <= 10^9
  • -10^9 <= target <= 10^9
  • Return any valid pair of indices in non-decreasing order.
Sample Tests
Test 1
Input
nums = [2, 7, 11, 15], target = 9
Expected
[0, 1]

2 + 7 = 9

Test 2
Input
nums = [3, 2, 4], target = 6
Expected
[1, 2]
Test 3
Input
nums = [3, 3], target = 6
Expected
[0, 1]
