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, -20, 3, -40], [47, 0, -47], [-1, -26], [-3, -33, 42, -21, 20], [9, 14, 13, 26, 35], [-8, -48, -30, 30], [42, 23], [19, 15, -50, -9, 29], [2, 39, 30, -27], [-8, -27, 37], [44, 14, 39, -10], [-2, -4, 26, -7, 3], [8, -36], [46, -24]]

SOLUTION: [800, 0, -26, 840, 364, -345600, 42, -50, 60, -8, -6160, 208, -288, -1104]

PROBLEM: [[-6, 49, 20], [-20, 8, -19, -9], [-21, 9, 15, -3, -36], [-46, 24], [11, 32, -12], [-38, -28], [-32, 17], [-46, -5, -39, -39], [-19, -9], [-49, 11], [43, 22, 28, -17, -40], [-23, 16]]

SOLUTION: [-120, -160, -36, -1104, -384, 1064, -32, -46, 0, 0, -24640, 16]

PROBLEM: [[43, -33], [-43, -40, 13, 50], [34, -5, 23], [7, 3, 12], [-15, 35, -38, -42, -36], [-45, -8], [-37, 34, -7], [-39, -32, 45], [27, -33], [-49, 1, 6, 8, -11], [39, 21, -49], [38, 23, -22, 39], [-23, 7, -40, -29, 25]]

SOLUTION:
[0, -2000, 34, 12, -57456, -8, 34, -32, 0, 48, 0, -836, -40]
