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: [[-6, -18, 49, 35], [16, 5, -12], [27, 39, -15, 29, 39], [41, 31, 16, 35], [-24, -30, 50, -42], [-8, -12, -29], [23, -41, -11, 23]]

SOLUTION: [108, -192, 0, 16, -1512000, 96, 0]

PROBLEM: [[33, 18, 35, -30], [33, -45], [-44, -4, 18, 38], [38, -22, -38], [25, -9, 0, 29], [8, -44, -5, -5, -25], [-16, 49, -31], [12, -35]]

SOLUTION: [-540, 0, 120384, 31768, 0, -352, -16, 12]

PROBLEM: [[-26, -11, 0, 14, 42], [24, -28], [41, -14, -23, -11, -19], [48, -12, 3, -28], [-19, 2], [-45, 8], [-9, 16], [47, 24, -18, 32, 27], [-42, 36, -50], [11, 5, 42], [-50, 17, 17, 3], [-11, -8], [-27, -48, -9], [28, -48]]

SOLUTION:
[0, -672, -14, 16128, 2, 8, 16, -13824, 75600, 42, -50, -8, -48, -1344]
