You will be given a definition of a task first, then an example. Follow the example to solve a new instance 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.

[[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Solution: [0, 72, -32]
Why? The first inner list has no even integers, so the first number in the output is 0. The second list has -6, -6, 2 for even integers so the second output is 72. The third list has -8, 4 as even numbers so the third output is -32. This is a good example.

New input: [[-43, -29], [30, -14, -25, -10, 39], [-47, 28, -49, -8, 19], [-37, -6, 1], [36, -5, -13], [-40, -8], [-46, -14, 10, -28, -5], [21, -50, 26, 10, 48], [35, -4], [50, 21], [47, -33, -35], [13, 11, -46], [-17, -29], [10, -33, -42, -48, -50]]
Solution:
[0, 4200, -224, -6, 36, 320, -180320, -624000, -4, 50, 0, -46, 0, -1008000]
