You will be given a definition of a task first, then some input of the task.
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.

[[-33, -41], [-30, -33, -9, 37], [-25, 0, -21, 8], [-13, 28, -1, -19, 2]]
