+# Shuffle the Array
+[Leetcode Link](https://leetcode.com/problems/shuffle-the-array/)
+
+## Problem:
+
+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:
+
+```
+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].
+```
+```
+Input: nums = [1,2,3,4,4,3,2,1], n = 4
+Output: [1,4,2,3,3,2,4,1]
+```
+```
+Input: nums = [1,1,2,2], n = 2
+Output: [1,2,1,2]
+```
+
+## Note:
+
+- `1 <= n <= 500`
+- `nums.length == 2n`
+- `1 <= nums[i] <= 10^3`
