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: [[-31, 46, -21], [7, 6, -34, -37, -35], [-41, -44], [38, -43, -18, -12, 39], [-33, -38, -14, 26], [28, -48], [-20, 12, -26, -12, 13], [47, 38, 40, -33], [1, 32, 43, -11, 21], [33, 0, 30, -26]]
Solution:
[46, -204, -44, 8208, 13832, -1344, -74880, 1520, 32, 0]
