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, 5, -1, 42, -33], [20, -47], [2, -19, 16], [39, 20], [11, 3], [-9, 16, 23, 33], [33, 12]]

SOLUTION: [42, 20, 32, 20, 0, 16, 12]

PROBLEM: [[42, 47, -40], [-10, 47], [-23, 24]]

SOLUTION: [-1680, -10, 24]

PROBLEM: [[-11, 31, -24, -11], [-24, -39], [22, -23, -34, 10], [-48, -46], [23, -39], [-14, -2, -14], [30, 6], [32, 6], [-27, -50, -48, -13], [7, -10, -41, 13], [-32, 12], [-27, -23], [-9, 14, 28], [1, 12, -26, 4, -27], [28, -42, -38]]

SOLUTION:
[-24, -24, -7480, 2208, 0, -392, 180, 192, 2400, -10, -384, 0, 392, -1248, 44688]
