In a One Drop coding screen, implement a function that returns the indices of two numbers in an array whose sum equals a target value.
Given an integer array nums and an integer target, return the indices of the two distinct elements such that nums[i] + nums[j] == target. You may assume exactly one valid answer exists, and you may not use the same element twice.
nums: list of integerstarget: integer[i, j] representing the indices of the matching pairExample 1
nums = [2, 7, 11, 15], target = 9[0, 1]nums[0] + nums[1] = 2 + 7 = 9Example 2
nums = [3, 2, 4], target = 6[1, 2]nums[1] + nums[2] = 2 + 4 = 62 <= len(nums) <= 10^4-10^9 <= nums[i] <= 10^9-10^9 <= target <= 10^9
