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: [[27, 7, 13], [-42, 16, 17, -28, -40], [-19, -2], [-26, 18, 25, -16], [16, 50, -40, -33, 38], [-39, -42, 28, -27], [-37, 29, 3, -15, 13], [25, 38, -23, 33], [-28, -9], [-32, -22, 44, -15], [-3, 27, -24, 32]]
