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, 37, -20], [13, 17, 13, -33, 2], [-8, 34, -44]]

SOLUTION: [-20, 2, 11968]

PROBLEM: [[-9, -26], [-26, 23, -3, -25, 5], [-28, -15], [45, -6, 12, 49, 45], [31, 22, -11], [41, -34, 18, -7, 31], [43, 23, -49, -34], [27, 0, -39, -40, 27], [-27, -4, -3, -32, -35], [-32, 11, 24, 11, -35], [42, -10, -43, -37], [-43, -2], [-28, -38, -17, 34, 19], [-46, -10]]
