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: [[-39, -3, 16], [-46, 24, -47, 7], [-35, -28], [12, 7], [50, 13], [9, 35, 0], [-25, -50], [-16, 13], [-42, -7, 41, 23, -22], [-31, 42]]

SOLUTION: [16, -1104, -28, 12, 50, 0, -50, -16, 924, 42]

PROBLEM: [[-37, -17, -31, -47], [33, 45, 21, 44], [-16, -49, 14, -46], [19, -50], [-35, -40, 7], [29, 30, -21, -48], [-37, 20, -30, -27], [46, -27, -7]]
