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: [[47, 22, 8], [15, 11, -26, 24], [-26, 19], [-24, 40, -36, -12], [37, -3, -45, -6], [40, 23], [12, -47, -48], [-38, -26, 20, -3, 10]]

SOLUTION: [176, -624, -26, -414720, -6, 40, -576, 197600]

PROBLEM: [[49, -43, -11, -2, 33], [25, 38, 11, 1], [36, 17, 42, 12], [39, 46, -33, -2, -17], [50, -1, 46, 10, 32]]

SOLUTION: [-2, 38, 18144, -92, 736000]

PROBLEM: [[10, 34], [-38, -11, 16], [-46, 10], [-16, -36], [-19, 41, -27], [-47, 32], [-7, -6, -25], [-45, -35, 27], [-40, -5, -8, -35], [-22, -19, -20, 22, -50], [50, 44, 16, -26, 4], [-44, -30], [29, 4, 41, -15]]
