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: [[34, 43, 22, -32, -43], [29, 29, 29], [13, -3, 16, -32, 7], [-15, 29, -13, -39], [49, 50, 10, 3, -4], [-47, -31, -15, -42, 38], [-32, 0, 27, 44], [-15, -8]]

SOLUTION: [-23936, 0, -512, 0, -2000, -1596, 0, -8]

PROBLEM: [[-21, -32, 1], [19, 31, -9, 40, 24], [49, -12, -36], [1, -17, -4, -47, 30], [-29, -38, -36]]

SOLUTION: [-32, 960, 432, -120, 1368]

PROBLEM: [[-46, 40, -11, 11], [0, 37, -33, 11, 42], [-49, 22, 50, -12, 35], [-7, -1, 4], [-36, 11], [6, -40], [39, -28], [22, 35, 43, 32], [29, 33, 2]]

SOLUTION:
[-1840, 0, -13200, 4, -36, -240, -28, 704, 2]
