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: [[-50, 49, -28], [-50, 39, 21, 44, -18], [-29, 5, 14, -7], [-13, 10], [27, -45, -14, -10, -36], [-41, -35, -48], [-25, -26, 38], [-7, -32, -35, 7, 48], [-6, -34, -28, -2], [-27, -24, 47, 30, -35], [22, -1, 49, -2, 38], [-31, 29], [4, -49, -46, -36, -14], [-40, 22], [-36, 19, -10, -45, 10]]

SOLUTION: [1400, 39600, 14, 10, -5040, -48, -988, -1536, 11424, -720, -1672, 0, -92736, -880, 3600]

PROBLEM: [[-33, 49, 15, 3], [49, -36, -17], [-5, 18, -4], [39, -24, 1, 49, -14]]

SOLUTION: [0, -36, -72, 336]

PROBLEM: [[-12, 33, -3, -4, 31], [-41, 6, 18], [48, -36, -3], [-31, -6, -41, 38], [-10, -45, -26, -29], [20, -38, -28, 19, 4], [23, -20, 44], [-15, 31, -35, 26, 28]]
