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: [[29, 40, 15], [34, 17, 34, -26], [-9, -13, 42, 42], [13, -1, 3, -22, -14], [-35, 19, -17, -48]]

SOLUTION: [40, -30056, 1764, 308, -48]

PROBLEM: [[-46, -13], [35, 15, 47], [-7, 36, 35], [41, -2], [26, 14, 35], [-47, -27, -29, 44], [16, -49, -11, 9], [37, 19, 48, -17]]

SOLUTION: [-46, 0, 36, -2, 364, 44, 16, 48]

PROBLEM: [[-48, 42, 21, -4], [-34, -6, 0, -5], [-24, 19, 32], [15, 24], [-46, 3], [3, 15], [-27, 4, 39, -34, -31], [18, -41, -29, -23], [23, -31, -33, -42, 34], [38, -14, 34, 45, 45], [-48, -20], [5, -28, 13, -43]]

SOLUTION:
[8064, 0, -768, 24, -46, 0, -136, 18, -1428, -18088, 960, -28]
