Q: 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.
[[-49, 50], [-50, -42, -17, 28], [-22, 46, -23, -46, 24], [1, 1, -36, 12], [-47, -3, -28], [-15, 39, 18, -4, -14], [-49, 17, 40, -25, 24], [11, -27, -13, -39, -15], [12, -22, 22], [-43, -43], [15, -38, -34, 49, -12], [-42, -14, 13, -48], [4, -37, 14, 27]]
A:
[50, 58800, 1117248, -432, -28, 1008, 960, 0, -5808, 0, -15504, -28224, 56]
