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, 29, 14, -36], [-35, -16], [-39, -2, -25, -36], [-28, -5, 33, 18, 35], [20, -32, -14, 38], [40, -27], [-1, 20, -26, 4, 24], [-37, -23], [-2, -19], [-15, -39, 12, -33], [26, -34], [-42, -7, -27, 30], [44, -48]]

SOLUTION: [-14112, -16, 72, -504, 340480, 40, -49920, 0, -2, 12, -884, -1260, -2112]

PROBLEM: [[-47, 4, 8, 23, 23], [-25, -38, 28], [-19, -20, -15], [-40, 13, -8], [1, -3, -44]]

SOLUTION: [32, -1064, -20, 320, -44]

PROBLEM: [[-19, -41, 23, -43, 28], [-11, -43, -26, -3], [-48, -1, 8], [10, -5]]

SOLUTION:
[28, -26, -384, 10]
