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.

[[-48, -44, -29, 43], [12, -40], [18, 11, -6], [-35, -49, -27], [18, -13, 40, 31, 8], [34, 42, 6], [-34, -13, 32, -11, 33], [36, 22, -30], [35, 37, -31, 6], [-30, -42], [26, -17, 45, 39, -26]]
Output:
[2112, -480, -108, 0, 5760, 8568, -1088, -23760, 6, 1260, -676]
