Solution: Concatenation of Array
Understand how to build a concatenated array by tracking each index of the original array and placing elements at corresponding positions. This lesson helps you learn a linear time and space solution that efficiently duplicates an array without extra passes or built-in utilities.

Statement
Given an integer array nums of length n, construct an array ans of length ans[i] == nums[i] and ans[i + n] == nums[i] for i n (0-indexed).
In other words, ans is formed by appending nums to itself.
Return the array ans.
