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: [[49, -43, -11, -2, 33], [25, 38, 11, 1], [36, 17, 42, 12], [39, 46, -33, -2, -17], [50, -1, 46, 10, 32]]

SOLUTION: [-2, 38, 18144, -92, 736000]

PROBLEM: [[-14, -2], [17, -19], [-44, -29, 37], [-17, -34, -47, 10], [-39, -14], [38, -14, 42], [24, 49], [17, 43, -26, 27], [-39, 50, -38, 50], [2, 22, 50, -2], [-48, -37, 7], [-36, -10, 23, -48, 4], [-7, -12, -16, -42, -45]]

SOLUTION:
[28, 0, -44, -340, -14, -22344, 24, -26, -95000, -4400, -48, -69120, -8064]
