TASK DEFINITION: In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.
PROBLEM: [[9, 3], [46, 35, 15, 28], [47, 16], [22, 20, 4, 21, -3]]

SOLUTION: [0, 1288, 16, 1760]

PROBLEM: [[3, 25, -42], [-4, 9, -36, -10, 22], [-43, 5, -16, -6, -14], [-47, -30, -9], [-44, -2, 20], [23, -37, 4, 27], [15, -30, 27, -39, 26], [-9, 33], [23, 26]]

SOLUTION: [-42, -31680, -1344, -30, 1760, 4, -780, 0, 26]
