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: [[-49, 5, -1, 42, -33], [20, -47], [2, -19, 16], [39, 20], [11, 3], [-9, 16, 23, 33], [33, 12]]

SOLUTION: [42, 20, 32, 20, 0, 16, 12]

PROBLEM: [[41, 11, 16, -47, 17], [-48, 24, -25, 26, 17], [48, -5, -28, -30, -26], [-31, 10], [-5, -37], [36, 43, -26, -34], [-36, 17, 27, 14], [-33, 38, 26], [39, 16, 34], [-36, -27]]

SOLUTION: [16, -29952, -1048320, 10, 0, 31824, -504, 988, 544, -36]

PROBLEM: [[-1, 50], [11, -42, -21, -25], [46, 7], [-33, 21, 5], [9, -38, 3], [39, -37, -38, -50, 50]]

SOLUTION:
[50, -42, 46, 0, -38, 95000]
