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: [[-49, 3, 15, 17, 0], [19, 38, -10, -31], [5, -34, 29, -20, -44], [-1, 48], [44, 49], [-35, 5, 7, -33]]

SOLUTION: [0, -380, -29920, 48, 44, 0]

PROBLEM: [[0, 43, 10, -26], [-28, 12, -40, 29, 11], [-5, -26, 28, -17]]

SOLUTION: [0, 13440, -728]
