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: [[16, -21, -6, 27], [11, -14, -41], [-43, 26, -12, 9, 47], [-5, -29, -21, 16], [38, 17], [-24, 22, 34, -5], [47, -31, 41, 38], [-35, -46, 23, -29], [37, -11], [-50, 11, 28], [11, -17], [-15, 6], [-24, 11]]

SOLUTION: [-96, -14, -312, 16, 38, -17952, 38, -46, 0, -1400, 0, 6, -24]

PROBLEM: [[-14, -14, 15], [6, 0, -34, -18], [40, 19, -28, -30], [4, 19, -16, -29], [-40, -21, 3, 44, 2], [-35, -16, -21, 22, 37]]

SOLUTION: [196, 0, 33600, -64, -3520, -352]
