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: [[-46, 5, -43, -49], [-8, 21, 15], [17, -27, -50, 40, -34], [49, 25, -33], [32, 6, -27, 26], [0, 30]]

SOLUTION: [-46, -8, 68000, 0, 4992, 0]

PROBLEM: [[37, 40, 35, 50, -35], [23, 0, -47], [-5, 38], [-13, 33, 19, 25], [-34, 30, 30], [1, -13, 44, -1, -30], [18, -9, -8], [7, -31, -21, 49, -1], [35, -43, 19, 39], [-29, 33, -48], [19, -44]]

SOLUTION: [2000, 0, 38, 0, -30600, -1320, -144, 0, 0, -48, -44]

PROBLEM: [[9, -5, -2, 5, 12], [25, 10, -48], [-35, -48, 12], [-47, -4, 0, 37], [33, 48], [-19, -35, 39], [-37, 18, -22, -20], [-29, -2, 29]]

SOLUTION:
[-24, -480, -576, 0, 48, 0, 7920, -2]
