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: [[-21, 48], [9, 37], [46, -29], [-32, -7, 45, -43, -32], [-35, 14, -42], [-45, 16], [-2, 24, 30, -42, 31], [9, -11, 10]]

SOLUTION: [48, 0, 46, 1024, -588, 16, 60480, 10]

PROBLEM: [[-42, -27, -46, -45], [45, -32], [-44, -8], [-23, 2], [15, 2, 17, 7], [27, 39, -38, -39, -9], [2, 46, 42, -33], [-47, 33, -50], [-9, -25, 8, 23, -1], [-46, -20, 27, 47, -10], [-13, 9, 22, 29, -40], [-45, -5, -30], [36, -20, -42], [-33, 39, -28, 20]]

SOLUTION: [1932, -32, 352, 2, 2, -38, 3864, -50, 8, -9200, -880, -30, 30240, -560]

PROBLEM: [[-18, -22, 40, -46], [-48, -46, -46, -11, -15], [34, -27, 19, -30, 21], [-30, 45, -34, 24], [40, -1, -25], [-9, -33, -43, 28], [-34, -42, -18, -34, -38], [-40, 25], [-34, 43, -35, 43, -31], [29, 45, 49], [-47, -38], [19, 44, 3, -10, -32], [-15, -23]]

SOLUTION:
[-728640, -101568, -1020, 24480, 40, 28, -33209568, -40, -34, 0, -38, 14080, 0]
