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: [[23, 12, 35, -33], [6, -37, -14, 23], [-25, -14], [12, -50, 11, -38, 36]]

SOLUTION: [12, -84, -14, 820800]

PROBLEM: [[-23, 13, -22, -20, -17], [-17, -4], [-24, 19, 5], [8, -49, -8], [29, 27, -41, 12], [-33, -17], [8, -48, 16, 43, 0]]

SOLUTION: [440, -4, -24, -64, 12, 0, 0]

PROBLEM: [[-2, 0], [35, 19, 2], [25, -8], [-20, -23, -2], [18, 20, -37, 21], [-3, -34, 47, 26, 8], [-12, 44, -26, -45, 21], [-49, -43], [-28, 7, 27], [26, 43], [-17, -26], [5, 46], [-11, 32, 27, 24, -44], [47, 2, -18, -24, -28]]

SOLUTION:
[0, 2, -8, 40, 360, -7072, 13728, 0, -28, 26, -26, 46, -33792, -24192]
