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: [[-38, -42, -30, 0], [29, 21, -11], [-30, -11, -29], [-43, -14, 19, 46], [-14, 47, 11, 30], [-11, 4], [-14, 42], [-43, 10, -47, -27]]

SOLUTION: [0, 0, -30, -644, -420, 4, -588, 10]

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]

PROBLEM: [[-1, -47], [18, 5], [-14, 10, -30, 11, -42], [-49, -37, 45, 30]]
