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: [[30, -24, -19, 29], [-1, -24], [26, 23, 27, 30, -23], [-17, 48, -43, 0], [40, -19, 21, 37], [37, -3], [-9, 24, 23, 36, -32], [-46, -13]]

SOLUTION: [-720, -24, 780, 0, 40, 0, -27648, -46]

PROBLEM: [[41, 49], [-26, 45, 8, 27, -23], [15, -9, 13], [-50, -44, -21], [46, 3, -31]]

SOLUTION: [0, -208, 0, 2200, 46]

PROBLEM: [[44, -49], [40, -40], [17, 46, -5, -17, 22], [15, 5, 0, -50, 26], [7, 17, -20, 23], [-10, -45, 32], [-42, 2, 12], [2, -38, 15, -46, 36], [-48, 17, 1], [-25, -31, -18, -35], [39, -29, 50]]

SOLUTION:
[44, -1600, 1012, 0, -20, -320, -1008, 125856, -48, -18, 50]
