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: [[-49, 5, -1, 42, -33], [20, -47], [2, -19, 16], [39, 20], [11, 3], [-9, 16, 23, 33], [33, 12]]

SOLUTION: [42, 20, 32, 20, 0, 16, 12]

PROBLEM: [[11, -25, -15, 25, -45], [20, -20, -35], [33, -10, 14], [-21, 50, -16, 49], [25, 11, -44, -33], [-49, 35, 13, 19], [38, 37], [-19, -18, -46]]

SOLUTION: [0, -400, -140, -800, -44, 0, 38, 828]

PROBLEM: [[19, 38, -13], [30, 16, 4], [12, -25, -49, -48, 9], [14, -32, 26, 5], [16, -36, -50], [34, 5, 32, 38, 8], [36, 20], [-44, 17, -23, -14, -44], [26, 21, 6], [-20, 48, -20], [-6, -9], [42, -8]]

SOLUTION:
[38, 1920, -576, -11648, 28800, 330752, 720, -27104, 156, 19200, -6, -336]
