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: [[-35, 16, -38, 27], [39, 49, 18, -23], [13, 41, -24], [31, -25, 29, -9], [13, -42, -20, 42], [-5, 2, -20, 39, 18], [46, -21, -18], [8, -8, -26], [-37, 24, 25, 2], [-21, 19, 13], [-29, -31], [0, -4, -37, 39], [28, -23, -40, -3], [-50, 29]]
Solution:
[-608, 18, -24, 0, 35280, -720, -828, 1664, 48, 0, 0, 0, -1120, -50]
