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.
Q: [[18, -11, -45], [-31, -10, 15, -32, 2], [-46, 15, 10, -31], [48, 21], [-28, -29, 41, -22], [24, -5, -39, -13], [-6, 12, -8], [-43, 45, 47], [12, -13, 48]]
A:
