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:
[[46, 46], [1, -11], [-10, 6, -11], [-32, -37, -50, 31]]

Ex Output:
[2116, 0, -60, 1600]


Ex Input:
[[7, -39, -8, -38, -50], [29, -39, -35, -40], [13, 2, -36, -37, -32], [12, -29, -22, 26], [-48, 35, -3], [4, 38, -42, 10]]

Ex Output:
[-15200, -40, 2304, -6864, -48, -63840]


Ex Input:
[[-22, -18], [-1, -28, 19], [-25, -13, -31, 5, -47], [-4, -47, 38], [-6, -48, 25], [3, -37], [10, 37], [-49, 25, -33, 10, 43], [-6, 21, -19], [50, 33, 33], [40, -8, -19], [-27, -31, -15, -14, -41]]

Ex Output:

[396, -28, 0, -152, 288, 0, 10, 10, -6, 50, -320, -14]
