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.
One example is below.
Q: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
A: [0, 72, -32]
Rationale: 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.
Q: [[38, 6, 34], [-9, -34, 15, 9, 9], [6, 42, -43], [17, -37, 39, -8, -42]]
A:
[7752, -34, 252, 336]
