/*Given a zero-based permutation nums (0-indexed), build an array ans of the same length where ans[i] = nums[nums[i]] for each 0 <= i < nums.length and return it.
Given a 0-indexed integer array nums which is a permutation of the first n natural numbers, return an array ans of the same length as nums such that ans[i] = nums[nums[i]] for each 0 <= i < ...
