 1 | // 1470. Shuffle the Array
 2 | // Solved
 3 | // Easy
 4 | // Topics
 5 | // Companies
 6 | // Hint
 7 | // Given the array nums consisting of 2n elements in the form [x1,x2,...,xn,y1,y2,...,yn].
 8 | 
 9 | // Return the array in the form [x1,y1,x2,y2,...,xn,yn].
10 | 
11 |  
12 | 
13 | // Example 1:
14 | 
15 | // Input: nums = [2,5,1,3,4,7], n = 3
16 | // Output: [2,3,5,4,1,7] 
17 | // Explanation: Since x1=2, x2=5, x3=1, y1=3, y2=4, y3=7 then the answer is [2,3,5,4,1,7].
18 | // Example 2:
19 | 
20 | // Input: nums = [1,2,3,4,4,3,2,1], n = 4
21 | // Output: [1,4,2,3,3,2,4,1]
22 | // Example 3:
23 | 
24 | // Input: nums = [1,1,2,2], n = 2
25 | // Output: [1,2,1,2]
