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: [[0, -14, 2, 35, -25], [-21, -38, 22, -39, 3], [-13, -47, 34, 50]]

SOLUTION: [0, -836, 1700]

PROBLEM: [[-45, 32], [-19, 12], [-5, 12, 29], [0, -13, 14, -38], [-2, -37, 16], [-9, 30, 38, 31, 47], [10, 45, -11, -6], [20, 47, 21, -18, 18], [6, 24, -31, 25], [41, -43, -42], [14, -25], [-7, 35, -7, 47], [46, -48, -33, 44, 37], [31, 49]]

SOLUTION: [32, 12, 12, 0, -32, 1140, -60, -6480, 144, -42, 14, 0, -97152, 0]

PROBLEM: [[-42, -28, 40, -9, -24], [-3, 27, -14, -38], [-13, 47], [45, 45, -35, 20], [32, -32, 48], [-15, -4, -39, -1], [-17, 16, -13], [3, 16], [-46, -37, 9, 35, -42], [39, 50, 4]]

SOLUTION:
[-1128960, 532, 0, 20, -49152, -4, 16, 16, 1932, 200]
