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: [[-46, 5, -43, -49], [-8, 21, 15], [17, -27, -50, 40, -34], [49, 25, -33], [32, 6, -27, 26], [0, 30]]

SOLUTION: [-46, -8, 68000, 0, 4992, 0]

PROBLEM: [[-20, -21], [49, 15, 47, -50, 14], [1, -3, 31], [41, -23], [-38, -35, 38, 17], [17, -22], [-35, 2, 46, 14], [-10, -11], [14, -44, 38, -35, 0], [-47, -22]]

SOLUTION: [-20, -700, 0, 0, -1444, -22, 1288, -10, 0, -22]

PROBLEM: [[14, -35], [34, 7], [40, -50], [-38, 14, 3], [20, 28], [-17, -15, 10, 28, 35], [-24, -17, 11, -2, 31], [36, 25, 40, 5, -43], [33, -41, 27, -24, 26], [8, -1], [-48, 36], [35, -16, 19, -47], [20, 29, -22, -37], [8, 5, -25, 36, -41], [-35, -46, -41, 21]]

SOLUTION:
[14, 34, -2000, -532, 560, 280, 48, 1440, -624, 8, -1728, -16, -440, 288, -46]
