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.

[[27, -24], [-35, -37, 4, 36], [18, 16], [14, -27, -26, 5, -34], [-19, 46, 14], [48, -6], [-11, -46, 32, 11]]
Output:
[-24, 144, 288, 12376, 644, -288, -1472]
