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: [[-10, -9, 41, 48], [25, 31, 28], [21, -40, 14], [-12, 34, -32, -37], [30, -45, 21, -4], [15, -23, -49, 50, 30], [33, -9, -13]]

SOLUTION: [-480, 28, -560, 13056, -120, 1500, 0]

PROBLEM: [[-7, 46, -33], [-5, 11, 34, -34, 28], [-24, 20, 33, -26, -49], [-35, 12, -50, 42, 26], [40, 20], [-21, 11], [39, -29, -36], [-17, 2], [36, 48, -13, 10, -48], [-29, -44], [-40, -39]]

SOLUTION: [46, -32368, 12480, -655200, 800, 0, -36, 2, -829440, -44, -40]
