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, -34, 16, 23], [-15, 1, -26, 24, -11], [-47, -38, 47, -36, -12], [-5, -35], [-24, 34, 39, -24, -28], [20, -25, -4], [11, -31, 48], [-41, 5, 5, 45, 31], [44, 29, -28, 4], [49, 26, 15], [-25, 20], [-23, 24, -10, -18]]
Answer:
[-544, -624, -16416, 0, -548352, -80, 48, 0, -4928, 26, 20, 4320]
