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.
