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: [[-33, 13, 13], [29, 18, -19, -1], [10, 29, 14], [25, -9, 39, -5], [-31, -33, 33, 47], [16, -48, 5], [9, 29, -36], [-38, -22], [34, 41, 43, 1], [-8, -49], [21, -40, -5], [39, -23], [43, 43, -5, -8, 40], [23, -47, 15, 3, 20]]
Output:
[0, 18, 140, 0, 0, -768, -36, 836, 34, -8, -40, 0, -320, 20]
