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: [[-23, 46, -50, 39], [1, -2, -36], [-30, 16, -27, -26], [-18, 15], [20, 44, -22, -9, -28], [-35, -6, 23, 33, 42], [49, -13, 2, 15, 33], [30, 39, -41, 41], [23, 8, -33, -50, 20], [-48, 34], [29, 49, -20]]

Solution: [-2300, 72, 12480, -18, 542080, -252, 2, 30, -8000, -1632, -20]
