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
[[47, -36, -47, 38], [-3, 41, 35, -4, 12], [-23, 13, 21, -40], [-28, 33], [27, 13, -15, -23], [42, 8, 13], [36, -42, -28, -49], [-1, -5, -17, -48, -1], [-5, 2, 47, -16, 24], [50, -13, 29, 12], [14, 1, -15, 24], [-29, -25], [6, -50, -50, -49], [-49, -44, 21, -33], [-40, 9]]
Answer:
[-1368, -48, -40, -28, 0, 336, 42336, -48, -768, 600, 336, 0, 15000, -44, -40]
