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: [[-15, -22], [-20, 45, 0], [10, -47, -17], [39, -32], [50, 3, 44, 44, -7], [13, -20, 36, -11], [-5, -11, 4], [24, 27, 50, 4], [28, -30], [-36, 25, 17, -24, 35], [-44, 33, 46, -24, 21], [-3, 21, 38], [-23, -28, 42, 11]]

SOLUTION: [-22, 0, 10, -32, 96800, -720, 4, 4800, -840, 864, 48576, 38, -1176]

PROBLEM: [[5, -8], [39, 31, 0, 28], [-22, -41, -50], [-13, 30, -12, 13, -3], [-2, 2, -14, -18, 5], [23, 23]]

SOLUTION: [-8, 0, 1100, -360, -1008, 0]

PROBLEM: [[35, -38, -20, -1], [-34, -47, -46], [42, 9, 50], [50, 23, -5, 36, 7], [-23, 28]]

SOLUTION:
[760, 1564, 2100, 1800, 28]
