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: [[2, 44, -17], [37, -39, -23, -31, 24], [41, 18, -46, 30, -29], [-10, 22, 24, 14], [5, -43, 17], [4, 36, -34, -13, -18]]

SOLUTION: [88, 24, -24840, -73920, 0, 88128]

PROBLEM: [[22, -32, 44, -38], [43, 20], [9, -19, -29, 10, 46], [21, -17], [-1, 20, -16], [27, -34, 18, 28], [-2, 44, 39, 8], [1, 12, -31, -24], [-50, -13, -2, 2], [9, -39, 11, -6]]

SOLUTION: [1177088, 20, 460, 0, -320, -17136, -704, -288, 200, -6]
