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.

[[35, 17, 7, -41, 22], [33, -17], [-50, 31]]
[22, 0, -50]

[[-32, 4], [10, -30], [-46, 43], [-12, -32, -7], [15, -22]]
[-128, -300, -46, 384, -22]

[[-28, -25, -24, 15], [-20, 3], [-1, -29], [49, 17, -9, -26], [37, 16, -32, -27, 6], [30, 31], [36, -39, 27, -50, 29], [-27, 17], [-21, 6, 5, -31], [-32, -14], [-21, -20, -25], [26, -8, 13]]

[672, -20, 0, -26, -3072, 30, -1800, 0, 6, 448, -20, -208]
