Instructions: 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: [[17, -41, 26, 27], [41, 12, 4], [-16, -11], [35, 12], [16, 24, 4, 19], [15, -49, 31, 42, 17], [46, -47, 4]]
Output:
[26, 48, -16, 12, 1536, 42, 184]
