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: [[30, -24, -19, 29], [-1, -24], [26, 23, 27, 30, -23], [-17, 48, -43, 0], [40, -19, 21, 37], [37, -3], [-9, 24, 23, 36, -32], [-46, -13]]

SOLUTION: [-720, -24, 780, 0, 40, 0, -27648, -46]
