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: [[49, 23, 46, -31, -34], [26, -44, 0], [3, -16, 10, -9], [-19, -23, 47, -41, -32], [4, 3, 13, -39], [25, 1, -42, -3, -48]]

SOLUTION: [-1564, 0, -160, -32, 4, 2016]

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]

PROBLEM: [[-49, 24], [-12, 38, 42, -6], [-26, 36, 5, -36, -7], [-27, 13], [-22, -29, -10, 46, 41], [28, -23, 42, 41], [39, 42, 15, 29], [-43, 6, -36, 34, 34], [-42, 4], [-12, 43]]
