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: [[-38, 0, 9, -17, 48], [9, 15, 43, -39], [34, 15, 26], [19, 17, 13]]

SOLUTION: [0, 0, 884, 0]

PROBLEM: [[-29, 37, 3], [21, -50], [-33, 47, -26, 21, -49], [5, -37], [30, -6], [-6, 8, -1, 4], [-38, -4], [15, -31, 34], [40, 32, 8], [49, -39, 29]]

SOLUTION:
[0, -50, -26, 0, -180, -192, 152, 34, 10240, 0]
