JuniorArray
Shuffle the Array
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 = 3Output
[2,3,5,4,1,7]Since x1 = 2, x2 = 5, x3 = 1, y1 = 3, y2 = 4, and y3 = 7, the answer is [2, 3, 5, 4, 1, 7].
Example 2
Input
nums = [1,2,3,4,4,3,2,1], n = 4Output
[1,4,2,3,3,2,4,1]Interleaving the first half [1, 2, 3, 4] with the second half [4, 3, 2, 1] gives [1, 4, 2, 3, 3, 2, 4, 1].
Constraints
- 1 <= n <= 500
- nums.length == 2n
- 1 <= nums[i] <= 10^3
