      1 //Shuffle an array where the input is (x1, x2, x3, y1 , y2, y3)
      2 //and the output is (x1 , y1, x2, y2 , x3, y3). 
      3 //The time complexity of my code is O(n) where n is the number
      4 //of values in the input array.
      5 //Runtime: 66ms Beats: 71.21%
      6 //Memory: 44.6MB Beats: 45.7%
