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: [[18, 7, 2, -50, 8], [8, 28, 32, 30], [13, -31, -9], [-8, 4], [21, 6], [15, -41, -1, -27, 44], [9, -39, -24], [-28, -18, -16, 9], [-45, 47, -44]]

SOLUTION: [-14400, 215040, 0, -32, 6, 44, -24, -8064, -44]

PROBLEM: [[-7, -29, -17, 49, -44], [-17, 19], [-35, -22, -2, 22], [36, 16, 9, 16, 13], [-3, 11, -6, 22], [19, 31, -35, -42, 46], [1, 28], [-42, 19, -4, 49], [42, 28, -21, -49], [-11, -33, -3, 7, -25], [-27, -38, -13, 15], [-40, -3, 26, 23]]

SOLUTION: [-44, 0, 968, 9216, -132, -1932, 28, 168, 1176, 0, -38, -1040]

PROBLEM: [[-6, 42, 7, 31, -40], [39, 38], [33, -35, 5, 29, 7], [-6, 34, -25, 24, -44], [-25, -9, -31, -32, -17], [-14, 20], [-29, 10, -23, 10], [38, 30, 41, 1], [1, 25, -17, -43, -29], [8, -14], [-38, -9, -18, 42, 44]]
