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: [[0, 12], [-42, -14, -36, -39], [13, -1, 50], [26, 11], [47, 49, 39], [9, -30, 45, 19], [-3, 44, -38, -31], [-37, -44, 14], [11, 13, -8, 46], [43, 49], [-15, -11, 30, 24], [5, -44, 11, 2], [50, 37, -46, 4], [20, 16, -30]]

SOLUTION: [0, -21168, 50, 26, 0, -30, -1672, -616, -368, 0, 720, -88, -9200, -9600]

PROBLEM: [[-45, -13, 30], [-35, -40, 40, 9, -15], [-15, 12, 44, -29, 0], [40, -41, 17, -2], [-38, 28, 7, -43, -3], [-47, 50, 45, 34], [-42, 40, -15]]

SOLUTION:
[30, -1600, 0, -80, -1064, 1700, -1680]
