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: [[21, 31, -37, 0], [23, 35, -43], [20, -45, 4, -3], [-41, 10, 1], [-44, -3, -49, -27], [43, 17, 28], [32, -40, 12, -46, 6], [-33, 17], [-38, 46, 14, -29, -15], [-3, -17, 24], [26, -43]]

SOLUTION: [0, 0, 80, 10, -44, 28, 4239360, 0, -24472, 24, 26]

PROBLEM: [[19, 43, 37, 28], [47, 1, 11, 14, 41], [25, -9, -37, 49, 4], [-35, 20, 8], [41, -20], [8, -31, -17, 1], [36, -38], [-19, 35, 6, 17], [1, -13]]
