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: [[17, -47, -14, -35], [-36, 20, 23, -8], [-32, -32], [15, 24, 45], [35, -43, 20, -1, -17], [6, 8, 39], [-10, 44, -25, -22], [48, -3, -3, 0]]

SOLUTION: [-14, 5760, 1024, 24, 20, 48, 9680, 0]

PROBLEM: [[49, -17, -34, 30], [-2, 24, -16, -13], [41, 20, -40, 26, -45], [-43, -4], [1, -28, -8, 38, -39], [0, -45, 2], [-23, -48], [-31, -27]]

SOLUTION: [-1020, 768, -20800, -4, 8512, 0, -48, 0]

PROBLEM: [[-40, -48], [-26, 45, -39, 33, 9], [18, 1, 18, 12, 44], [-34, -39, -14]]

SOLUTION:
[1920, -26, 171072, 476]
