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: [[-22, 23, 33], [20, -46, -21], [2, -23, 17, -6, -21], [4, 20, -21, 44, 43]]

SOLUTION: [-22, -920, -12, 3520]

PROBLEM: [[-46, -42, 17, 28], [19, -46, -43, -15], [-31, -18, 46, 26], [38, -9, -47, -17, -13], [-30, -23, 5], [-18, 21], [10, -33, -38, -15, 3], [-44, 17], [28, 6, 50, -9], [-6, 40, 17, -17], [-6, -18], [20, 37, -26, -37, 42], [-22, -2, 29, -27]]
