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: [[-6, -18, 49, 35], [16, 5, -12], [27, 39, -15, 29, 39], [41, 31, 16, 35], [-24, -30, 50, -42], [-8, -12, -29], [23, -41, -11, 23]]

SOLUTION: [108, -192, 0, 16, -1512000, 96, 0]

PROBLEM: [[-6, -22], [41, -1, 11, -12], [-41, 25, 20, -43], [20, -3, -40, -25, 18], [28, 0], [-49, 31, 30, 10, 14], [3, -16, 42, -2, -7], [6, -27, -33]]

SOLUTION: [132, -12, 20, -14400, 0, 4200, 1344, 6]

PROBLEM: [[1, -26], [-11, 4, -23, 28], [50, 26, -32], [-9, -1, -26, 32, -9], [-15, 25, 41, -16, 7], [6, 34], [12, 18, 50, -30], [-44, -31], [-20, 16], [30, -40], [35, 18, 19, -34, -40], [-36, 9, -38]]

SOLUTION:
[-26, 112, -41600, -832, -16, 204, -324000, -44, -320, -1200, 24480, 1368]
