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: [[29, 7, 31, -4, 18], [-33, -13, 28], [-49, -24], [-20, 26, -49]]

SOLUTION: [-72, 28, -24, -520]

PROBLEM: [[-38, 35, 29, 26], [-38, -24, -14, -40, -26], [-41, 46, -12, -6], [10, 31, -38, -8, -28], [-25, 10, -27, -1], [-14, 39, -50, -30], [-17, -8], [-41, 49, 18, -25, 44], [-26, 46, -9, -19, -17]]

SOLUTION: [-988, -13278720, 3312, -85120, 10, -21000, -8, 792, -1196]

PROBLEM: [[-29, 47, -29], [7, 24, 25, 46], [35, -23], [-49, 25, 16], [16, -12, -12], [-39, 3, -34, -2], [-2, -13, -49], [-12, -23, -24, 4, -9], [-16, 36], [12, -45, 28, 25], [13, 9, -10], [45, 42], [-18, -17, 32], [16, 46, -2, -20, 28]]

SOLUTION:
[0, 1104, 0, 16, 2304, 68, -2, 1152, -576, 336, -10, 42, -576, 824320]
