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: [[-24, -39, 47], [-2, 26, 10, 25], [-34, -16, 40, -16], [47, -24, 46, -38, -10], [-6, -39, 19], [-44, -36, -14, 2]]

SOLUTION: [-24, -520, -348160, -419520, -6, -44352]

PROBLEM: [[15, 12, 9], [42, 49], [-39, -29, -18], [32, -2, -16], [-40, 33], [29, -48, -11, 47], [7, 30], [43, -26], [-10, -11, 2, -13, 14], [25, 46]]

SOLUTION: [12, 42, -18, 1024, -40, -48, 30, -26, -280, 46]

PROBLEM: [[-29, 2, 0, 6, 2], [50, -12], [23, 13, 30, 50], [7, -26, -1, 26, 48], [-11, -22, -17, 7, 36], [48, -49, 4, 18], [15, 42, -10], [44, 45, -44], [20, 20], [28, -30], [32, 10, 47, -3, -30], [23, 23, 33, -11, -31], [-29, 43, 19, 20, 11], [-8, 42, 40, -10]]

SOLUTION:
[0, -600, 1500, -32448, -792, 3456, -420, -1936, 400, -840, -9600, 0, 20, 134400]
