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, 14], [-42, 2, 18], [40, -33, 39, 16, -24], [-37, -43, -29, -18], [-27, -46], [-38, -26, 41]]

SOLUTION: [644, -1512, -15360, -18, -46, 988]

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]

PROBLEM: [[19, 27, 5, -27], [-28, 13, 18, 1, 3], [-13, 43, -8], [9, -20], [-35, -4, -34, -3, -1], [-45, 12, 2], [9, 0, 23], [-21, -2], [-18, 50, -31, -10, -8], [15, -45, 42]]

SOLUTION:
[0, -504, -8, -20, 136, 24, 0, -2, -72000, 42]
