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: [[-6, -22], [41, -1, 11, -12], [-41, 25, 20, -43], [20, -3, -40, -25, 18], [28, 0], [-49, 31, 30, 10, 14], [3, -16, 42, -2, -7], [6, -27, -33]]

SOLUTION: [132, -12, 20, -14400, 0, 4200, 1344, 6]

PROBLEM: [[32, -48, -17], [-22, 28], [11, 2]]
