You will be given a definition of a task first, then some input of the task.
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.

[[-5, -12, -43, 23, 46], [42, 13, -30], [-17, 32, 8], [38, 14], [43, 36, -38, -18, 32], [-21, 23, -50, -10, 41], [-41, 1, -38, -28, -21], [-22, -3, 29], [8, 10, -50, -19, -26], [-42, 43, -18, 29, 44], [-19, -17, -35, 45], [17, 38, 43], [2, 35, 12], [28, 9, 36, -10, 6]]
Output:
[-552, -1260, 256, 532, 787968, 500, 1064, -22, 104000, 33264, 0, 38, 24, -60480]
