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: [[22, 44, -35], [22, -18, -29], [2, 24, 24], [-6, -49, 25, -44], [-31, 4, -42], [8, 45, 2], [-10, 21, -11, -25, 37], [-46, 1, -8]]

SOLUTION: [968, -396, 1152, 264, -168, 16, -10, 368]

PROBLEM: [[0, -32], [-6, -5, 37, 6], [13, -33, 47, 44], [8, 35, 19, 48], [35, 48, 35, -42], [11, -35], [-2, -43, 12, -10, -17], [-6, -24, 31], [-12, -14, -48, -36]]

SOLUTION: [0, -36, 44, 384, -2016, 0, 240, 144, 290304]

PROBLEM: [[-28, 32], [-35, 4, -41], [-50, 47, -2, 42], [21, 35, 40]]

SOLUTION:
[-896, 4, 4200, 40]
