1470. Shuffle the Array (Easy) (https://leetcode.com/problems/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]. Constraints: 1 <= n <= 500 nums.length == 2 * n 1 <= nums[i] <= 10

function shuffle(nums: number[], n: number): number[] {
  const result = new Array(n * 2);
  for (let i = 0; i < n; i++) {
    result[i * 2] = nums[i];
    result[i * 2 + 1] = nums[i + n];
  }
  return result;
}
 
// Local check:
console.log(shuffle([2, 5, 1, 3, 4, 7], 3))
console.log(shuffle([1, 2, 3, 4, 4, 3, 2, 1], 4))
console.log(shuffle([1, 1, 2, 2], 2))

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]
