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: [[37, 40, 35, 50, -35], [23, 0, -47], [-5, 38], [-13, 33, 19, 25], [-34, 30, 30], [1, -13, 44, -1, -30], [18, -9, -8], [7, -31, -21, 49, -1], [35, -43, 19, 39], [-29, 33, -48], [19, -44]]

SOLUTION: [2000, 0, 38, 0, -30600, -1320, -144, 0, 0, -48, -44]

PROBLEM: [[-38, -29], [9, -32, 23, 9, -2], [48, 16, 16]]

SOLUTION: [-38, 64, 12288]

PROBLEM: [[27, 35, 35, 39], [41, 13, -39], [-6, 42, 11, -31], [-24, 4, -27, -44, -27], [6, -23], [25, 5], [37, -45]]

SOLUTION:
[0, 0, -252, 4224, 6, 0, 0]
