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.

[[-22, -48, 8, -23, 25], [-16, 30], [-35, 28], [-37, 29], [0, -10, 3, 45, -46], [-37, 19], [42, -39, -29], [-24, 47, -22, 1, 1], [17, -4], [-33, -42, -50, 10, -40], [41, 13, 25, 7], [-13, 3, -22, -11, -42], [-41, 17, 28, -21, 17], [-32, 14, 10, -27]]
Output:
[8448, -480, 28, 0, 0, 0, 42, 528, -4, -840000, 0, 924, 28, -4480]
