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, -10, -49, -8], [-49, -13], [-35, 9, -26, 50], [-43, -50, 9, -43, 20], [-30, -41], [-40, 42, -20, 31, 50], [-50, 1, -31], [42, -33, -14, 25, 47], [-45, -39], [29, 13, 27, -49], [18, 46], [-27, -50, -24], [-32, 39, -13], [-1, 10, 41, 25, -26]]
