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: [[2, 44, -17], [37, -39, -23, -31, 24], [41, 18, -46, 30, -29], [-10, 22, 24, 14], [5, -43, 17], [4, 36, -34, -13, -18]]

SOLUTION: [88, 24, -24840, -73920, 0, 88128]

PROBLEM: [[30, -10, 13, 27], [16, -31, -26, 12, -6], [14, 49, 15, -31, -21], [-30, -11, 49, -36], [15, -27], [27, 5, 29], [-4, 47, 13, 6], [-3, 0, 11, 2], [12, 27]]

SOLUTION: [-300, 29952, 14, 1080, 0, 0, -24, 0, 12]

PROBLEM: [[19, -3, 2, 47], [-50, -33, -28, -31, 49], [35, 6], [-29, 20, 48, 24], [17, -27, 35, 43, -6], [43, 47]]

SOLUTION:
[2, 1400, 6, 23040, -6, 0]
