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:
[[-50, 1], [-35, 28], [-44, -28, -37, 45], [17, 29, -26], [21, 4]]

Ex Output:
[-50, 28, 1232, -26, 4]


Ex Input:
[[23, -22, 8], [-9, 49, -1], [-26, 18, -19], [6, 26, 30, 39, -32]]

Ex Output:
[-176, 0, -468, -149760]


Ex Input:
[[31, 47, -5], [-10, -35, -30, 34, 22], [47, -22, -10, -14, 2], [50, 36, 2], [-47, -34, -23], [42, -7], [-5, 34, 9], [-46, 43, 47, 9, 49], [12, -13, -48], [-50, -21, 44]]

Ex Output:

[0, 224400, -6160, 3600, -34, 42, 34, -46, -576, -2200]
