>Concatenation of Array

Easy

Given an integer array 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 = [nums[0],nums[1],nums[2],nums[0],nums[1],nums[2]]
+- 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 = [nums[0],nums[1],nums[2],nums[3],nums[0],nums[1],nums[2],nums[3]]
+- ans = [1,3,2,1,1,3,2,1]
+
