1470\. Shuffle the Array

Easy

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]

**Example 3:**

**Input:** nums = [1,1,2,2], n = 2

**Output:** [1,2,1,2]

**Constraints:**

*   `1 <= n <= 500`
*   `nums.length == 2n`
*   `1 <= nums[i] <= 10^3`
