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: [[1, 50, -3], [7, 23, 15], [-3, 12, 4, -22, -34], [-13, 48], [16, -41, -37, 43, 41], [-24, 13, 28, 8], [-30, -2, 12], [-1, 13, -50], [49, 11, -11, -34], [-15, 5, 8], [-26, 21]]

SOLUTION: [50, 0, 35904, 48, 16, -5376, 720, -50, -34, 8, -26]

PROBLEM: [[19, -31, 34], [-24, -21, 48, -33], [26, 33, 29, 17, 5], [-41, 29, 46], [-20, 16, 50], [-8, 49, 4, -42], [-1, -27, -23, 11, -25], [-23, -45], [-26, 16], [45, 5, -9, -27], [-22, 38, 15], [-41, 49, 47, -50], [47, 9], [-17, -33]]

SOLUTION: [34, -1152, 26, 46, -16000, 1344, 0, 0, -416, 0, -836, -50, 0, 0]

PROBLEM: [[1, 46, 0], [-49, 22, -21, 4], [1, 31], [-49, 18, 50, 14], [-40, -2, -18], [-28, 31, -42, -34, 5], [-20, 25, -11, -47], [11, 36, 13, -14, -22], [-7, -16, -5, 27, 14], [48, 48, -5, 20], [43, 39, -14], [21, -8], [-29, -48, 16, -8]]

SOLUTION:
[0, 88, 0, 12600, -1440, -39984, -20, 11088, -224, 46080, -14, -8, 6144]
