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: [[19, 46, -37], [-12, 14, 46, -34, 24], [-50, -4], [40, -12, -34], [3, 22, 5, -24], [43, 22], [25, 48, -34, 5, 2], [45, 33, -7], [-15, 50, 30, 40], [18, -20], [27, 0, 29]]
