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: [[23, 12, 35, -33], [6, -37, -14, 23], [-25, -14], [12, -50, 11, -38, 36]]

SOLUTION: [12, -84, -14, 820800]

PROBLEM: [[31, 43, 9, 3], [-27, 50, 18, -46], [15, -43], [25, 36, -48, -12, -23], [-14, -35, -41, -23, -30], [-12, -38], [38, -20], [-25, 5, 29], [25, 31, 45, -50], [35, 17]]
