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, -31, 34], [-24, -21, 48, -33], [26, 33, 29, 17, 5], [-41, 29, 46], [-20, 16, 50], [-8, 49, 4, -42], [-1, -27, -23, 11, -25], [-23, -45], [-26, 16], [45, 5, -9, -27], [-22, 38, 15], [-41, 49, 47, -50], [47, 9], [-17, -33]]
