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: [[17, -18, 9], [-42, -12], [39, -2, 31, 14], [-16, -9, -20], [19, -30], [47, -29, -40]]

SOLUTION: [-18, 504, -28, 320, -30, -40]

PROBLEM: [[-25, 37, -13, -24], [-31, -17, 9, -21, -41], [2, -41, 25, -42, 48], [-26, -36, -15, 33, 25], [41, 17, 45, 3], [37, -43, -30], [12, 27, -35, 7, -3], [33, -9], [22, -4, 43, 35], [-47, -46, -26], [23, -45, 2, -39], [6, 18, -29, 13, 13], [-9, -39], [3, -15, -11, 0], [-4, 17]]

SOLUTION: [-24, 0, -4032, 936, 0, -30, 12, 0, -88, 1196, 2, 108, 0, 0, -4]

PROBLEM: [[-16, -45, 4, 43], [-30, 32, 43, -27, -40], [12, -44, -45, -41], [-29, 47, -41, -38], [-19, -33], [22, -32, 42], [-35, 37, 40], [34, -38, 41, 0, 29], [40, -27, -2, 18, -31]]

SOLUTION:
[-64, 38400, -528, -38, 0, -29568, 40, 0, -1440]
