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]. |
|
|
|

|
|
|
|
|
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]. |
