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.
Example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Example solution: [0, 72, -32]
Example 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.

Problem: [[-21, -8], [-12, 6, -35, 18, -12], [2, -49, -31], [-32, -50, 42, 41, -15], [-13, -39, 7], [-25, 42], [-1, 20], [44, -39, -24, 39], [4, -15], [21, -24, -25], [6, 32, 43, 15], [-22, 48, 14, -19, 45], [-12, 13], [1, -17, 4, -6], [45, -14, 44]]

Solution: [-8, 15552, 2, 67200, 0, 42, 20, -1056, 4, -24, 192, -14784, -12, -24, -616]
