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: [[10, -9, 27], [-18, -2, 2], [-44, 26, -34], [29, -2], [-49, -23, 8], [7, -49, -44], [-31, 2, -4, -35, 17], [-40, -12, -31, 19, 29]]

SOLUTION: [10, 72, 38896, -2, 8, -44, -8, 480]

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, -36, -39, 48], [6, -1, 47, -34, 31], [38, 15, -35, 30, -35], [-29, 12, -36, 28], [-20, 41, -21]]

SOLUTION:
[-1728, -204, 1140, -12096, -20]
