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: [[-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]

PROBLEM: [[13, 7, 20], [-30, 36, -7, -19], [-37, -22], [25, 13], [22, -31], [18, 33, -17, -3, -30], [37, -33, 40, 14, 13], [11, -16]]

SOLUTION: [20, -1080, -22, 0, 22, -540, 560, -16]
