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: [[49, -50, 23], [3, 37, -23, -30], [30, 17, -35, -22, -20], [43, -12, -10, 46], [5, 8], [27, 12, 29, 29, -25], [-11, 43, 11, 8], [-22, 43, 4, -38, 22], [39, -42], [-38, 32, -12, -46], [-46, 39, -47, -6, 21], [-45, 13, 23, -43], [-38, -18, -30], [-47, 43, 5, -38], [33, 14]]

SOLUTION: [-50, -30, 13200, 5520, 8, 12, 8, 73568, -42, -671232, 276, 0, -20520, -38, 14]

PROBLEM: [[47, 22, 8], [15, 11, -26, 24], [-26, 19], [-24, 40, -36, -12], [37, -3, -45, -6], [40, 23], [12, -47, -48], [-38, -26, 20, -3, 10]]

SOLUTION: [176, -624, -26, -414720, -6, 40, -576, 197600]

PROBLEM: [[-15, -8, 45, -1], [-38, 48, 46, -17], [-41, -33, 14], [-1, -17, -2, 33], [25, -40, -23, 26, -37], [-15, 21, -32, -33], [-17, -7], [-35, -26, -39], [-25, 16], [15, 10, 23, -41], [-38, 46], [-38, 25], [12, 37, -16], [42, 15, 34]]

SOLUTION:
[-8, -83904, 14, -2, -1040, -32, 0, -26, 16, 10, -1748, -38, -192, 1428]
