1. Here is an array containing both numbers as well as other arrays, which in turn contain numbers and arrays:

array=[ 1, 2, 3, [4, 5, 6], 7, [8, [9, 10, 11, [12, 13, 14] ] ], [15, 16, 17, 18, 19, [20, 21, 22, [23, 24, 25, [26, 27, 29] ], 30, 31 ], 32 ], 33 ] 

What is a recursive function that prints all the numbers (and just numbers).
