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: [[35, 17, 7, -41, 22], [33, -17], [-50, 31]]

SOLUTION: [22, 0, -50]

PROBLEM: [[47, 10], [5, 3], [40, 0], [3, 30, -35], [-2, 3], [33, 7, 42, 12, 29], [-27, 17, -46, 10], [45, -9, -4, -28], [44, 38, 26]]
