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: [[24, 37, 48], [36, 47, -44, 43, 9], [25, -19, 20, 17], [-48, -9, 33, 12, 9], [50, 47, -23], [2, -47, 6, 1], [-16, 21, 0, -49], [-23, 13, -44], [49, -15, -49, 4, 31]]

SOLUTION: [1152, -1584, 20, -576, 50, 12, 0, -44, 4]
