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: [[29, 23, -11], [0, -1], [31, -4, 18, -19], [33, 33], [-9, -31, -26, -45], [5, -38, 9, -6, 44], [3, 29, 17, -15, 46], [4, 12]]
Output:
[0, 0, -72, 0, -26, 10032, 46, 48]
