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, -10, -13, 43], [50, -1, 48, -29], [-36, 35], [-3, 34, 4, -45, 17], [-44, 34, 31]]

SOLUTION: [-10, 2400, -36, 136, -1496]

PROBLEM: [[9, -24, 11, -5, -8], [20, -9, 34, 1, -45], [-1, 38, 7, 6, 40], [15, 1], [48, 8, 47, -32, 9], [-7, -14, -26], [21, -21, -9], [-3, 33]]

SOLUTION: [192, 680, 9120, 0, -12288, 364, 0, 0]

PROBLEM: [[20, -49, -39], [-41, 12, 27, 27], [-17, -7]]

SOLUTION:
[20, 12, 0]
