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: [[15, -47, 16, 34, -3], [-23, -25, -14, -25], [-22, -25, -27, -39], [-38, 49, 21, -5, -14], [9, 14, -11], [18, -35, 17, 43], [5, 32, -7], [9, -17, -8], [-46, 43, -30, -29], [-5, -30, 20, -44, 3], [21, 7, 12, 35], [34, 2, -36, 22, 31], [19, -31, 46, -7]]

SOLUTION: [544, -14, -22, 532, 14, 18, 32, -8, 1380, 26400, 12, -53856, 46]

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]
