+/*Question-
+Given the array nums consisting of 2n elements in the form [x1,x2,...,xn,y1,y2,...,yn].
+Return the array in the form [x1,y1,x2,y2,...,xn,yn].
+
+Example 1:
+
+Input: nums = [2,5,1,3,4,7], n = 3
+Output: [2,3,5,4,1,7] 
+Explanation: Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is [2,3,5,4,1,7].
+Example 2:
+
+Input: nums = [1,2,3,4,4,3,2,1], n = 4
+Output: [1,4,2,3,3,2,4,1]
+
+Constraints:
+
+1 <= n <= 500
+nums.length == 2n
+1 <= nums[i] <= 10^3
