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, 2, 10], [-8, 18, -35], [0, 21, -23, -40], [10, 27]]

Ex Output:
[20, -144, 0, 10]


Ex Input:
[[-37, -41, 17], [29, -44, 35, -34, -46], [26, 9, 28], [0, -16, 24, -18], [13, 18, 42], [29, -21, -27], [-10, -16, 12, -39, -22], [4, -3], [-29, -23]]

Ex Output:
[0, -68816, 728, 0, 756, 0, -42240, 4, 0]


Ex Input:
[[-5, 45, 40, 1], [-19, 1, -16], [46, 38, 8], [35, 25, 32, 46, 16], [-29, 41, -24, -49], [24, -15, -14], [-12, -44, -19, -34]]

Ex Output:

[40, -16, 13984, 23552, -24, -336, -17952]
