+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]
