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: [[4, 39], [-49, -6, 5, 41, 25], [-40, -45, -33], [28, -23, 45], [8, -32], [-8, -43, -4, -24], [-19, -43, 6, 2, -28], [35, -28, 37, 21], [45, 41], [-34, 27, 25, 5], [-23, -1]]

SOLUTION: [4, -6, -40, 28, -256, -768, -336, -28, 0, -34, 0]

PROBLEM: [[-8, -1, -12], [38, 17, -12], [35, -40, -6], [-5, -15, 43, -42], [-46, -38, 46, -49, 30]]

SOLUTION: [96, -456, 240, -42, 2412240]

PROBLEM: [[45, -36, 22, -36, 31], [5, -3, 37], [37, 18, 4, -13, -26], [14, -28, 50, -48], [-40, -15], [35, 5, 19, 2, -35], [-2, -21, 45, -4], [9, 40], [12, -4, 7, -43, -2], [-30, 13, 36, -23], [-10, -39, 49], [-32, -12, -27, -46, 17], [-33, 27]]

SOLUTION:
[28512, 0, -1872, 940800, -40, 2, 8, 40, 96, -1080, -10, -17664, 0]
