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: [[50, -26, 6], [-40, 6], [19, -40], [36, 32, -10, 22, 1], [-18, -14], [-44, 27], [19, -8], [-15, 33, 42, -24, -37], [43, 28, -19]]

SOLUTION: [-7800, -240, -40, -253440, 252, -44, -8, -1008, 28]
