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: [[-25, 31, 45], [-25, -45, 2, 1, -48], [9, -46, 45, -12, 47], [-41, 22, -17], [-43, 39]]

SOLUTION: [0, -96, 552, 22, 0]

PROBLEM: [[8, -30, -35, 47], [-5, -2, -24], [-19, 39, 33], [-10, 32, 19], [-46, -15], [14, 3, -15], [-38, 41, 24], [-15, -47, 34, 17], [28, 16, -23], [18, -10, -15], [34, -20, -13]]

SOLUTION: [-240, 48, 0, -320, -46, 14, -912, 34, 448, -180, -680]

PROBLEM: [[-1, 45, 30, -13], [39, 19], [50, -38, 46, -16, -26], [-6, -27, -27, 38], [-30, -25, 40, -26, 9]]

SOLUTION:
[30, 0, -36358400, -228, 31200]
