Write a function called interleave to interleave two row arrays of equal length. Ex: For row arrays arrayOne and arrayTwo, the output row array is arrayThree = [arrayOne(1), arrayTwo(1), arrayOne(2) ,arrayTwo(2), …]. The function should work for rows of any length. Hint: Create a new array by concatinating arrayOne and arrayTwo, then flattening the array to finally end up with the desired row array. No internal functions are needed. Ex: Flattening a=[1,2;3,4] gives [ 1; 3 ; 2; 4]. Restrictions: For and while loops should not be used.
