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: [[37, 10, -3], [45, 39, 43, 9, 25], [-13, -40, -29, -43, -3], [47, 16, 14, 34], [-29, -29, -9, 49], [-35, 1, -28, -13], [3, 19, 50, 7], [39, -7, -11], [47, -4, 32, 23, 41], [-28, 23], [-9, 14], [-11, 7, -24, 14, -13], [-20, -13, 0]]

SOLUTION: [10, 0, -40, 7616, 0, -28, 50, 0, -128, -28, 14, -336, 0]
