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: [[-14, 50, 5, 50], [-49, -2, -30], [-35, 24, -20], [13, 0], [-29, -26, -44], [-11, 21, 48], [17, 22], [-41, 30, -11, -9], [32, -23, 40, 37, 11], [-37, 45, -35, -26, 17], [-39, 7, 48, -37, 14], [-13, 36], [-31, -31]]
