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: [[50, -26, 6], [-40, 6], [19, -40], [36, 32, -10, 22, 1], [-18, -14], [-44, 27], [19, -8], [-15, 33, 42, -24, -37], [43, 28, -19]]

SOLUTION: [-7800, -240, -40, -253440, 252, -44, -8, -1008, 28]

PROBLEM: [[4, -43, -6, 30], [9, 17, -1, -2, -43], [-44, 12]]

SOLUTION: [-720, -2, -528]

PROBLEM: [[-26, 12, -50, -44, -40], [0, -41], [-29, -22], [37, 50, 3, -46], [25, 22], [25, 35, -11, 14], [9, 4, -48, 36, 21], [-17, -42, 9], [46, -41, 6, -22, 8], [5, -13], [-27, 19, -46, -45, 12], [40, -15], [-31, 13, -48], [15, 43]]

SOLUTION:
[27456000, 0, -22, -2300, 22, 14, -6912, -42, -48576, 0, -552, 40, -48, 0]
