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: [[-26, 33, 12, -48, 9], [13, 30], [-26, 23, -42], [39, -35, 33], [14, -11], [1, -14, 15, -29]]
Output:
[14976, 30, 1092, 0, 14, -14]
