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: [[-35, 39], [-23, -1, -39], [-29, -23], [47, -4, -6], [-27, -50, 39, -35], [44, -33, 40, -48], [-10, 23, 40, -30], [-3, -48]]

SOLUTION: [0, 0, 0, 24, -50, -84480, 12000, -48]

PROBLEM: [[-8, -44, -13, 2, 22], [17, 38], [43, -11, 17, -32, 45], [-6, 39, 32, 36, -45], [29, 24, 4, 21], [-33, -44, -43], [-44, 34], [8, 47, 5, 27, 10], [41, 45, 12, -7]]

SOLUTION: [15488, 38, -32, -6912, 96, -44, -1496, 80, 12]

PROBLEM: [[-23, -33], [-39, 37, -36], [-4, -24], [-46, 5], [28, -9, -50, 20], [-43, 45, -43], [-19, -14, 13, 24, -21]]
