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: [[23, -48, -18], [9, 47, 33, 32, -22], [-30, -23, 9, -25, -17], [-39, 8, 27], [3, -34, 8, -42]]

SOLUTION: [864, -704, -30, 8, 11424]

PROBLEM: [[7, -10, -13, 43], [50, -1, 48, -29], [-36, 35], [-3, 34, 4, -45, 17], [-44, 34, 31]]

SOLUTION: [-10, 2400, -36, 136, -1496]

PROBLEM: [[-48, -9], [25, 33, 16, -15, 7], [43, -10, -48, -8], [21, -19, -5], [-10, 14, 46, 2], [45, -10, 13, -37, -24], [14, 1, 35, 38], [-34, -30], [-7, 23, -2, -8, 24], [47, -21, -41, 42], [-24, -6, 30], [27, -29], [-23, -39], [12, 16, 9, -4]]

SOLUTION:
[-48, 16, -3840, 0, -12880, 240, 532, 1020, 384, 42, 4320, 0, 0, -768]
