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: [[-22, 24, 33, -31], [-29, -28, 2, -32], [-38, 27], [-22, -45, 40, -40], [-5, 16, 47, 38, -2], [-33, 19, -12, 3], [15, -14, 8, 47, 15], [42, -30, -27], [-33, -32, 12], [22, -24, -23], [-38, 50, 29], [18, -27], [2, 27, -16, -18], [-7, -18, -47, -23, -23]]
