TASK 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.
PROBLEM: [[10, -37], [-37, -50, -2], [22, -16, -30], [2, 5, 39, 46, 21], [-17, -21, -2, -8], [-14, -34, -12], [-39, -29, 34, -38, 49], [-41, 48, 29], [-4, -19, -27, 32, 7]]

SOLUTION: [10, 100, 10560, 92, 16, -5712, -1292, 48, -128]

PROBLEM: [[-46, 5], [9, 48, 17], [-6, -3, -26]]

SOLUTION: [-46, 48, 156]

PROBLEM: [[-43, 37, 19, -31, -27], [-3, -9], [-22, 43, -32, 15], [1, 39], [44, -13, 25, -40], [-43, 8], [4, -22, 1, 12, 2], [1, 1, -8, -39, -38]]

SOLUTION:
[0, 0, 704, 0, -1760, 8, -2112, 304]
