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: [[-13, -41, 49], [-14, 24, 24, -44], [-10, -12, 26, -32, 38], [-1, -9], [-48, -31], [-5, 25, 33, -5, 7], [-23, -50, 38, 24, -5], [-17, -46, -9, 36]]

SOLUTION: [0, 354816, -3793920, 0, -48, 0, -45600, -1656]

PROBLEM: [[-40, -27], [2, 39, -27, 14], [-34, 25, -37, 49], [18, -13, 43], [-11, -23], [49, -14, 27, -20], [-27, 14], [-14, 18, 1, -42, 33]]

SOLUTION: [-40, 28, -34, 18, 0, 280, 14, 10584]
