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.

Ex Input:
[[-10, 39, -31, 2], [-45, 4, 34], [-19, 25, 47, -4], [15, -3], [-10, 18, 50, 30]]

Ex Output:
[-20, 136, -4, 0, -270000]


Ex Input:
[[-5, 2], [22, 16], [33, 6, -36, -35], [-20, 1, -35, 25], [-32, 10, 41], [-45, 32], [38, 50, 47, 9], [-50, 50, -5, 29], [-11, -8, 42, -45], [30, 44, -43]]

Ex Output:
[2, 352, -216, -20, -320, 32, 1900, -2500, -336, 1320]


Ex Input:
[[-17, -11, 5], [-44, -33, 49, -4, -31], [-41, 19, -13, 8]]

Ex Output:

[0, 176, 8]
