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
[[-40, 28, 26, 50], [48, 12], [-14, -3, -25, -15], [6, 22, -7, 40], [-3, 37], [-28, 13, 8, -41, 45], [-15, -4, -35, -18, 40], [9, -45, -47], [-49, 42, 37, -25, -47], [31, 15], [-8, 38, -46, -36], [40, 23, 13], [-41, -7], [-31, 30, 26, 1]]
Answer:
[-1456000, 576, -14, 5280, 0, -224, 2880, 0, 42, 0, -503424, 40, 0, 780]
