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: [[-23, -33, 19, -41, -11], [17, -28, -32, 28], [8, -5], [15, -33, -18, -41], [-47, 12, 11, -7, 23], [21, 34, 44], [32, -4, 25, -33], [-37, 15, 24, 47], [41, -8], [-41, -20, 20, -14], [21, 28], [23, 29]]
