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: [[-21, 48], [9, 37], [46, -29], [-32, -7, 45, -43, -32], [-35, 14, -42], [-45, 16], [-2, 24, 30, -42, 31], [9, -11, 10]]

SOLUTION: [48, 0, 46, 1024, -588, 16, 60480, 10]

PROBLEM: [[29, -30, 45, 0, 38], [-11, 42, -18], [-48, -13, 21, 20], [18, -17, -31, -12], [39, -31], [7, 21], [8, 23, -21, -4, -18], [-36, 21]]

SOLUTION: [0, -756, -960, -216, 0, 0, 576, -36]

PROBLEM: [[-37, -13], [-8, -44], [38, -18, 25, 1], [-37, 31, -18, 34]]

SOLUTION:
[0, 352, -684, -612]
