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: [[0, -27, -3, 22, 38], [22, 50, -13, -38], [12, 9, -36], [-45, -36, 4, -26, 15], [-41, 34, 3], [11, -28, -34, 19], [-27, -3, -29, -15, -45], [36, -14, -17], [-4, -28, -7], [7, -28, -45, -6], [8, 3, 32, -40, 23]]

SOLUTION: [0, -41800, -432, 3744, 34, 952, 0, -504, 112, 168, -10240]
