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: [[-2, 12], [14, 47], [4, 0, -4, 4, 30], [-46, -24, 13], [48, -30], [40, -41, -40]]

SOLUTION: [-24, 14, 0, 1104, -1440, -1600]

PROBLEM: [[-45, 50, 40, -22], [-4, -31], [22, 22, 15], [-33, -41, 46, -24], [22, -10, 35, -23], [22, 8, 9, 19, 41], [-4, -17, -49, -24, -21], [4, -44], [-19, 31], [-40, 24, -31], [-14, 29, -15, 32]]

SOLUTION: [-44000, -4, 484, -1104, -220, 176, 96, -176, 0, -960, -448]

PROBLEM: [[-50, -19], [4, -37, -12, 17, 11], [-10, -26, -47, 17], [5, -24, 13, -31, 2], [-5, 4, -17], [17, -18, -45, -1, 15], [5, -12, -19, -3, -35], [8, 3], [30, 5], [18, 14, 1], [31, -2, -28, 40], [39, -7, 30, -43], [-46, 20]]

SOLUTION:
[-50, -48, 260, -48, 4, -18, -12, 8, 30, 252, 2240, 30, -920]
