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:
[[49, 23, 46, -31, -34], [26, -44, 0], [3, -16, 10, -9], [-19, -23, 47, -41, -32], [4, 3, 13, -39], [25, 1, -42, -3, -48]]

Ex Output:
[-1564, 0, -160, -32, 4, 2016]


Ex Input:
[[12, -6, -21, 33], [-8, -29, -44, 38], [-45, -21, 18], [8, -17, -26, 50], [0, 18, -38], [2, -24], [-8, 34, 25, -10]]

Ex Output:
[-72, 13376, 18, -10400, 0, -48, 2720]


Ex Input:
[[-37, 28, -2, -3], [-13, -6], [46, 11, -18, -31]]

Ex Output:

[-56, -6, -828]
