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: [[28, 49], [-9, -22, 27, -43], [-20, 15, -6, 31, -14]]

SOLUTION: [28, -22, -1680]

PROBLEM: [[49, -50, 23], [3, 37, -23, -30], [30, 17, -35, -22, -20], [43, -12, -10, 46], [5, 8], [27, 12, 29, 29, -25], [-11, 43, 11, 8], [-22, 43, 4, -38, 22], [39, -42], [-38, 32, -12, -46], [-46, 39, -47, -6, 21], [-45, 13, 23, -43], [-38, -18, -30], [-47, 43, 5, -38], [33, 14]]
