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: [[10, -25, 29, -10], [-8, 31, 35, -48, -1], [-33, -29, 16], [3, -2], [-37, 19, -5, 16], [-34, -47, -33], [-30, 0, 37, 1], [-37, 45, 39, -5], [-47, 20, -20, -30, -29], [-37, -27, 46], [-17, -26, -35, 14], [-5, -38, -1, 35, 44]]

SOLUTION: [-100, 384, 16, -2, 16, -34, 0, 0, 12000, 46, -364, -1672]

PROBLEM: [[-32, 2, -20, -30, 0], [11, 11], [-29, 50, -14, 42], [0, 32, 39], [-46, 45, 24, -49], [-45, 47, 49, -43, -33], [23, 2], [36, 37, -10, 27], [-43, -25], [20, -46, 41], [20, -38], [-1, -1, 20], [-14, 20, 4, 12], [39, 47], [9, -27]]

SOLUTION:
[0, 0, -29400, 0, -1104, 0, 2, -360, 0, -920, -760, 20, -13440, 0, 0]
