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: [[49, -17, -34, 30], [-2, 24, -16, -13], [41, 20, -40, 26, -45], [-43, -4], [1, -28, -8, 38, -39], [0, -45, 2], [-23, -48], [-31, -27]]

SOLUTION: [-1020, 768, -20800, -4, 8512, 0, -48, 0]

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]]

SOLUTION: [54096, -46, -21528, 38, -30, -18, -380, -44, 8400, -240, 108, -21840, 44]
