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: [[0, 12], [-42, -14, -36, -39], [13, -1, 50], [26, 11], [47, 49, 39], [9, -30, 45, 19], [-3, 44, -38, -31], [-37, -44, 14], [11, 13, -8, 46], [43, 49], [-15, -11, 30, 24], [5, -44, 11, 2], [50, 37, -46, 4], [20, 16, -30]]

SOLUTION: [0, -21168, 50, 26, 0, -30, -1672, -616, -368, 0, 720, -88, -9200, -9600]

PROBLEM: [[-17, 15, 1], [-46, -14], [-11, 4, 43], [-22, 16], [3, -6], [38, 39], [-29, 36, -4], [7, -5, -7, -34], [3, 38], [25, 34, -27, -29, -44], [-22, 4, -24], [43, 20, 29], [14, 0]]

SOLUTION: [0, 644, 4, -352, -6, 38, -144, -34, 38, -1496, 2112, 20, 0]

PROBLEM: [[-49, -43, 33, -30], [45, -4, -15, 11], [-41, -36], [2, -8, 28, 32], [30, -36], [41, -2, -18]]

SOLUTION:
[-30, -4, -36, -14336, -1080, 36]
