Definition: 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.
Input: [[14, 1], [42, -32, -43, -16, -1], [49, 31, -46], [-9, -17], [-44, -36], [23, 3, -49, 33, 19], [-24, 43, 27, 14, 21], [45, -3, 46, -6]]
Output:
[14, 21504, -46, 0, 1584, 0, -336, -276]
