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: [[-23, -22], [7, -46], [-5, -1, -49, -1], [15, -6], [-39, -42, -25, -4], [-2, 1, -40], [-33, -29, -18, 33, 48], [-5, -12, 44, -38, 9], [-50, -49, 44, -37, 47]]
