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: [[-11, 18, -12, -30, 23], [-18, 33, 40, -18, 19], [-16, -5, -43], [-34, -49]]

SOLUTION: [6480, 12960, -16, -34]

PROBLEM: [[-18, -41], [49, 44, 23, 39], [-17, -36, -41, 42, -43], [25, -27, 6, 39, 26], [47, -36, 30, -50], [-28, -4, -4, 38, -6], [41, 17], [-19, 44, 39], [-37, 19, 33, 4], [-9, -41, 20, -49], [41, -10, 49, 10, -49], [31, 43], [38, -16, -29, -20, 3], [-17, -16, 2, -50]]

SOLUTION: [-18, 44, -1512, 156, 54000, 102144, 0, 44, 4, 20, -100, 0, 12160, 1600]

PROBLEM: [[35, 18, -10, 17, 13], [-32, 18, 2, 4], [-27, 42, 24], [-50, -26, 42], [1, -7, -28, -43], [3, 5, 27, -6, -28], [-2, 5, -14, -43, 43], [20, -43, 27, -18], [45, 38], [5, 12, 3, 9], [21, -17, -23, 8, -10], [-39, -10, -6, 17, 27], [-50, -43], [8, -32, -48], [-5, 3, 40, 38]]

SOLUTION:
[-180, -4608, 1008, 54600, -28, 168, 28, -360, 38, 12, -80, 60, -50, 12288, 1520]
