    1929 - Concatenation of Array\.

    Easy

    Given an integer array nums of length n, you want to create an array ans of length 2n where ans[i] == nums[i] and ans[i + n] == nums[i] for 0 <= i < n ( 0-indexed ).

    Specifically, ans is the concatenation of two nums arrays.

    Return the array ans.

    Example 1:

    Input: nums = 1,2,1

    Output: 1,2,1,1,2,1

    Explanation: The array ans is formed as follows:

    • ans = [nums0,nums1,nums2,nums0,nums1,nums2]

    • ans = 1,2,1,1,2,1

    Example 2:

    Input: nums = 1,3,2,1

    Output: 1,3,2,1,1,3,2,1

    Explanation: The array ans is formed as follows:

    • ans = [nums0,nums1,nums2,nums3,nums0,nums1,nums2,nums3]

    • ans = 1,3,2,1,1,3,2,1

    Constraints:

    • n == nums.length

    • 1 <= n <= 1000

    • 1 <= nums[i] <= 1000
