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: [[-40, 39, 47], [32, -22, 29, 4], [-27, -11], [42, 26, 20, -12, 28], [-19, 46, 1], [-24, -38], [-32, 34, -44], [-1, 49], [-6, 42, 16], [2, 42, -29, 7, 22], [8, -47, -42, -20]]

SOLUTION: [-40, -2816, 0, -7338240, 46, 912, 47872, 0, -4032, 1848, 6720]

PROBLEM: [[0, -20, 25, 3], [-27, -3, -16, 14], [29, -42, 30, 49], [48, -45, -11], [13, 31, -12, 36], [-47, -22, -13, -33, -13], [-29, 42, -1, 7], [-29, 47, -4], [-45, -28, 8, -13], [30, -35, -1], [-5, 35, 22], [33, 8, -43, 29, -20], [-24, 36, -34, 15]]

SOLUTION:
[0, -224, -1260, 48, -432, -22, 42, -4, -224, 30, 22, -160, 29376]
