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: [[18, -39, -15], [-15, 23, 38], [-9, 37], [-16, -1, 28], [48, 3], [34, 19, -19, 46], [37, 26, -12, 12], [-37, -2, 0]]

SOLUTION: [18, 38, 0, -448, 48, 1564, -3744, 0]

PROBLEM: [[3, 18, -24, 48], [22, 0], [-31, 41], [-20, 31, 23], [3, 32], [46, -45, 0], [9, -19], [10, -22, 23, 17], [41, 42], [34, 44, -24], [17, 29], [26, 27], [41, -5]]

SOLUTION: [-20736, 0, 0, -20, 32, 0, 0, -220, 42, -35904, 0, 26, 0]
