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: [[-44, 50], [11, 19, 20, 36, -32], [0, 37, 13, -21, -9], [23, 42, 21], [-18, 32, 42], [35, 18, -40, 1, -7], [18, -8, 42], [6, -33], [49, 33, 32, -20], [-40, 21, 50], [-17, 8, 24, 2, -26], [7, 30, -25, -34, 27], [-39, 26, 43, -22]]

SOLUTION: [-2200, -23040, 0, 42, -24192, -720, -6048, 6, -640, -2000, -9984, -1020, -572]

PROBLEM: [[8, 27], [47, -6, -15, 5, 47], [-16, -48, 0, 37, -44], [-21, -20, 13, -47], [-38, -47], [-33, -19, 44, 24, 9], [47, -15], [-20, 5, -13, -18], [32, -27, 21, -34, 3], [-49, 38, 25]]

SOLUTION: [8, -6, 0, -20, -38, 1056, 0, 360, -1088, 38]
