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, -49, 33, -19, 25], [23, -9], [-10, -30]]

SOLUTION: [0, 0, 300]

PROBLEM: [[0, 50, 16, -48, 7], [-2, -21, 12, 44], [20, -45, 14, 47], [-48, 10, -17, 34, 21]]
