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.
[[-38, -27, 28, -49], [15, 26, 37], [9, 21, 35, 23, -16], [-18, 45], [10, -14, -17], [-35, 6], [21, 18, -40, -24], [-20, -27, -26], [-36, 7, 11, -15], [-46, -15], [3, 12, 27, -11], [19, -19], [-41, -38, -36, -12, 15], [-34, -47, 16], [-50, 27]]
A:
[-1064, 26, -16, -18, -140, 6, 17280, 520, -36, -46, 12, 0, -16416, -544, -50]
