# Solving Leetcode Interviews in Seconds with AI: Shuffle the Array


	# Introduction
	In this blog post, we will explore how to solve the LeetCode problem "1470" using AI. LeetCode is a popular platform for preparing for coding interviews, and with the help of AI tools like [Chatmagic](https://www.chatmagic.app), we can generate solutions quickly and efficiently - helping you pass the interviews and get the job offer without having to study for months.

	# Problem Statement
	> 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 

	# Explanation
	Here's a solution to the problem of shuffling an array in the specified manner:

*   **Approach:**
    *   Create a new array to store the shuffled elements.
    *   Iterate through the first half of the input array (x1 to xn).
    *   For each element xi, append it to the new array, followed by the corresponding yi from the second half of the input array.

*   **Complexity:**
    *   Runtime: O(n), Storage: O(n)

	
	# Code
	```python
	def shuffle(nums: list[int], n: int) -> list[int]:
    """
    Shuffles an array of the form [x1,x2,...,xn,y1,y2,...,yn] to [x1,y1,x2,y2,...,xn,yn].

    Args:
        nums: The input array.
        n: The number of elements in the first half of the array.

    Returns:
        The shuffled array.
    """
    shuffled_nums = []
    for i in range(n):
        shuffled_nums.append(nums[i])
        shuffled_nums.append(nums[i + n])
    return shuffled_nums
