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: [[10, 3, -49, 43], [-31, 14, -20, -3], [48, 2, 45], [-39, -23, -30], [43, 47, 11, 26, 5], [14, -40, -19, -41], [6, 0, 41, -42, 26], [43, -49, -50], [-21, -1], [39, -29, -45, 20]]

SOLUTION: [10, -280, 96, -30, 26, -560, 0, -50, 0, 20]
