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: [[-30, -27, 29], [30, -34, -5, 22], [5, 15], [21, -36, -50, -22], [36, 8], [-12, -36, 11, -6, -8], [-5, -5, 12], [39, 42, -35, -42], [28, 38, 8], [44, -10, -5, -22, -32], [-3, -48, 40, -33, -9], [-46, -25, 31, -21], [-28, -50], [-8, -46, 50, -10, -8], [-27, 2, 41, 19]]

SOLUTION: [-30, -22440, 0, -39600, 288, 20736, 12, -1764, 8512, -309760, -1920, -46, 1400, 1472000, 2]

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: [[28, 0, -37], [-32, -37], [34, -37], [9, 22, 32, -1, -38], [26, 7, -14], [-4, -18, 24], [-50, -18], [-47, 19], [-48, -48, -45, 7, -46], [-42, 0, -1]]

SOLUTION:
[0, -32, 34, -26752, -364, 1728, 900, 0, -105984, 0]
