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, 35], [47, 10], [-12, 30], [-7, 31, -41], [25, -1, 2, 44, -13], [31, -19, -25, 6, -3]]

SOLUTION: [-46, 10, -360, 0, 88, 6]

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: [[29, -32, -36], [4, 41, 15], [19, 13, -35], [39, 18], [10, -1, 45, 37, -25], [-22, -21, 5, -13], [-14, 38], [-33, -49], [-18, 50]]

SOLUTION:
[1152, 4, 0, 18, 10, -22, -532, 0, -900]
