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: [[-25, 31, 45], [-25, -45, 2, 1, -48], [9, -46, 45, -12, 47], [-41, 22, -17], [-43, 39]]

SOLUTION: [0, -96, 552, 22, 0]

PROBLEM: [[-2, 16, 28], [-47, 8, -31], [-43, 45, 17, -9], [24, 42]]

SOLUTION: [-896, 8, 0, 1008]
