Shuffle the Array
Description
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
Solution(javascript)
/**
* @param {number[]} nums
* @param {number} n
* @return {number[]}
*/
var shuffle = function(nums, n) {
let arr = [];
for(let i = 0; i < n;i++){
arr.push(nums[i])
arr.push(nums[i+n])
}
return arr
};
