* Testcase Example: '[2,5,1,3,4,7]\n3'
*
* 给你一个数组 nums ,数组中有 2n 个元素,按 [x1,x2,...,xn,y1,y2,...,yn] 的格式排列。
*
* 请你将数组按 [x1,y1,x2,y2,...,xn,yn] 格式重新排列,返回重排后的数组。
*
*
*
* 示例 1:
*
* 输入:nums = [2,5,1,3,4,7], n = 3
* 输出:[2,3,5,4,1,7]
* 解释:由于 x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 ,所以答案为 [2,3,5,4,1,7]
*
*
* 示例 2:
*
* 输入:nums = [1,2,3,4,4,3,2,1], n = 4
* 输出:[1,4,2,3,3,2,4,1]
*
*
* 示例 3:
*
* 输入:nums = [1,1,2,2], n = 2
* 输出:[1,2,1,2]
*
*
*
*
* 提示:
*
*
* 1 <= n <= 500
* nums.length == 2n
* 1 <= nums[i] <= 10^3
*
