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: [[-31, -27, -17, 46, -31], [17, 25, -2, 49, -31], [4, -38], [-48, -35, 18, -32], [13, 39, 25, 30], [38, 29, -3, 43, -26], [23, -21, -16, 24, 33]]

SOLUTION: [46, -2, -152, 27648, 30, -988, -384]
