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.
One example is below.
Q: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
A: [0, 72, -32]
Rationale: 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.
Q: [[29, -24, -39], [30, 17, 30, 38], [-23, -47, -32, 45, 12], [46, -45, 14], [21, 9], [-47, -40], [-40, 10, -32, 17, -50], [-1, -43, -38, 22, 21], [37, -5, 15], [-28, 25, 30, 39, -39], [-47, 15, -19, 31, 28]]
A:
[-24, 34200, -384, 644, 0, -40, -640000, -836, 0, -840, 28]
