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
[[-49, 36, -46], [47, 12, 25], [9, 48, -42, -10], [-28, -25, -49, 32, -19], [-24, -3], [20, -31, 25], [16, 37, 15, -41, 46], [-36, 44, 39], [12, -26]]
Answer:
[-1656, 12, 20160, -896, -24, 20, 736, -1584, -312]
