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: [[-27, -15, -29], [-30, 44, 42, -2, 31], [-20, -21], [49, 36, 49], [-36, -45, 44, -47, -34], [41, 37, -29, 23, -42], [25, 46, -12, 49, -49], [-22, 1], [-3, 21, -20, -48], [-39, -9, 26, 22]]
