In a Meta-style coding interview, implement a function that finds two distinct elements in an integer array whose sum equals a given target. Return their indices, not the values.
nums: a list of integerstarget: an integer[i, j] such that nums[i] + nums[j] == target and i != jYou may assume exactly one valid answer exists, and you may not use the same element twice.
Example 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 = 6Example 3
nums = [3, 3], target = 6[0, 1]3 values are at different indices, so both can be used.2 <= len(nums) <= 10^5-10^9 <= nums[i] <= 10^9-10^9 <= target <= 10^9
