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, -43, -11, -2, 33], [25, 38, 11, 1], [36, 17, 42, 12], [39, 46, -33, -2, -17], [50, -1, 46, 10, 32]]

SOLUTION: [-2, 38, 18144, -92, 736000]

PROBLEM: [[-18, -37, 41], [14, 18, -23, 43, 28], [47, -46, 35], [-17, 46, -5, 29, 48], [-18, -17, 37, 39, -36], [12, -35], [-21, -24, -2, -26, -24], [-30, 48, -18]]

SOLUTION: [-18, 7056, -46, 2208, 648, 12, 29952, 25920]

PROBLEM: [[-11, 28, 50], [-11, 31, 37, -21], [0, -12, 35], [30, 39, -11], [46, -1, -18], [42, -36, -31], [-30, 38, 46, -19], [-38, -7], [21, 15, 13, -13]]

SOLUTION:
[1400, 0, 0, 30, -828, -1512, -52440, -38, 0]
