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: [[-28, 14], [-9, 23], [-37, 17, -30, 30, -5], [37, -39, 29], [22, 2], [44, -39, -14, -46, 14], [31, -27, 17, -40, 36]]

SOLUTION: [-392, 0, -900, 0, 44, 396704, -1440]

PROBLEM: [[42, -31], [-46, -10, 45, -17, -21], [27, 27, 42, 29, 14], [-37, 14, 11], [-38, -17, 3, 40], [-2, -44, 34], [-40, -17], [24, 37, 50, 26], [47, 25, 19], [-41, -46, -29, -11], [35, 45], [-27, -13, 41, -12], [43, 3, -11, -37]]

SOLUTION: [42, 460, 588, 14, -1520, 2992, -40, 31200, 0, -46, 0, -12, 0]

PROBLEM: [[12, 6, -20], [-18, -10], [-49, -1], [-39, 15], [12, -29, -4, 6, 47], [-29, 5, -13, -31, -2], [39, 13, -20, 17], [8, 39, -34, 17, 28], [-39, -46, 32, 30, 18], [-8, 49, 26], [-41, -5, 9, -36, -11]]
