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: [[24, -25, 11], [36, -21, -33, -17, 27], [41, -45, -1, -50], [40, -31, 20, -13, -45], [47, 7], [-21, 0, 22], [21, -16, 21, 33, 5]]

SOLUTION: [24, 36, -50, 800, 0, 0, -16]

PROBLEM: [[-15, 21, -15, -36, 14], [-48, 29, 33, 14, -17], [-30, 39, -24, -2, 46]]

SOLUTION: [-504, -672, -66240]

PROBLEM: [[31, 43, 9, 3], [-27, 50, 18, -46], [15, -43], [25, 36, -48, -12, -23], [-14, -35, -41, -23, -30], [-12, -38], [38, -20], [-25, 5, 29], [25, 31, 45, -50], [35, 17]]

SOLUTION:
[0, -41400, 0, 20736, 420, 456, -760, 0, -50, 0]
