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.
Example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Example solution: [0, 72, -32]
Example explanation: 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.

Problem: [[-37, -17, 33, 23], [4, -2, -50], [19, 31], [-2, -1, -19, -36], [13, -12, 49, -8, -46], [46, 35], [26, -16, 47, -36, 14], [-48, 41, -37, -11, -50], [-13, -21, 43, -2, -19], [-18, -17, -24, 44]]

Solution: [0, 400, 0, 72, -4416, 46, 209664, 2400, -2, 19008]
