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: [[29, 40, 15], [34, 17, 34, -26], [-9, -13, 42, 42], [13, -1, 3, -22, -14], [-35, 19, -17, -48]]

SOLUTION: [40, -30056, 1764, 308, -48]

PROBLEM: [[10, -9, 27], [-18, -2, 2], [-44, 26, -34], [29, -2], [-49, -23, 8], [7, -49, -44], [-31, 2, -4, -35, 17], [-40, -12, -31, 19, 29]]

SOLUTION: [10, 72, 38896, -2, 8, -44, -8, 480]

PROBLEM: [[-30, 9], [-49, -25, 23], [-17, 7, 18, -26, 15]]

SOLUTION:
[-30, 0, -468]
