Detailed Instructions: 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.
See one example below:
Problem: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Solution: [0, 72, -32]
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: [[7, -47, 5, 21], [37, -2, -10], [1, 4, -28, 48, -40], [-11, 19, 35, 7, -31], [-5, -19, 31, -47], [-35, -46, -7], [-2, 38], [-6, -14, -5, 50, -35], [9, 21], [50, 7, -35, -37, 48], [-39, -11, -18, -25, -40], [-41, -34]]
Solution:
[0, 20, 215040, 0, 0, -46, -76, 4200, 0, 2400, 720, -34]
