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: [[-20, -14, -39], [-47, -16, 27], [-46, -2, -34], [5, 28, -43, 26, 46], [35, -23, 19, -27], [7, 8, 28, 37, -23], [-41, -13]]

SOLUTION: [280, -16, -3128, 33488, 0, 224, 0]

PROBLEM: [[-41, -34, -7, -18], [-43, -33, 8], [33, 12, -19]]

SOLUTION: [612, 8, 12]

PROBLEM: [[-8, 11, 30, -9, 5], [10, -1, 30, 35, -16], [-13, -13, 49], [25, -19, 8]]

SOLUTION:
[-240, -4800, 0, 8]
