Part 1. 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.
Part 2. Example
[[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Answer: [0, 72, -32]
Explanation: The first inner list has no even integers, so the first number in the output is 0. The second list has -6, -6, 2 for even integers so the second output is 72. The third list has -8, 4 as even numbers so the third output is -32. This is a good example.
Part 3. Exercise
[[34, -17, -38, 47, -45], [-48, -42, 31, 16, -10], [-35, 33, -3], [19, 42], [-38, 26, 30, -43], [-48, 28, 26, -41], [-20, -20, 34], [31, 11, -5], [46, -37], [-31, 30], [22, -11], [-34, 46, 31, -6, 20]]
Answer:
[-1292, -322560, 0, 42, -29640, -34944, 13600, 0, 46, 30, 22, 187680]
