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: [[-7, 1, 45, -26, -4], [-50, 34, 27], [-6, -6], [-3, 19], [14, 49, 31, -26, 22], [-35, 21, 48], [6, -12, 3, -43, 27], [12, 28, -10, 42, -16], [49, -40, 19, 3, 48], [-37, -47, 8], [-50, 16, -6, -36], [19, -4], [24, 37], [14, 5, -46, 12, 16]]

SOLUTION: [104, -1700, 36, 0, -8008, 48, -72, 2257920, -1920, 8, -172800, -4, 24, -123648]

PROBLEM: [[23, -22, 8], [-9, 49, -1], [-26, 18, -19], [6, 26, 30, 39, -32]]

SOLUTION: [-176, 0, -468, -149760]

PROBLEM: [[-8, 3, -23, 17, -28], [0, -8, 24, -25], [44, 14, -21, -45, -35], [-48, 50, -2], [5, -43, 18, 24, 29], [-17, 6, -25, -36], [-8, -36, 20, -27, -15], [18, -7], [40, -24, 4, 45, -5], [41, 45, -17, 43], [44, 46, 18, 12], [7, -20], [20, 5]]

SOLUTION:
[224, 0, 616, 4800, 432, -216, 5760, 18, -3840, 0, 437184, -20, 20]
