Instructions: 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.
Input: [[-31, 49, 32], [16, -39, 16, 42], [-12, 26, 2], [13, -3, -11], [-19, -34, -44]]
Output:
[32, 10752, -624, 0, 1496]
