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: [[31, -16], [28, 38, 28, 5, 42], [28, -33, -11], [-12, 30], [40, 31, 25, 9], [-4, 38, 1, -39], [-3, -14, -43, -43, 15], [29, -1, 34], [-18, 18, 22, 2], [-30, -21, -18, -44], [-27, 15, -21, 31], [-39, 14], [40, 0, -22], [-23, -35, -33], [-19, 1, 39, 10]]

SOLUTION: [-16, 1251264, 28, -360, 40, -152, -14, 34, -14256, -23760, 0, 14, 0, 0, 10]

PROBLEM: [[-18, -47, -47, -6, -8], [24, -17, 48, 24], [-47, -3, -6, -4], [6, -38], [35, -25, 14], [-41, 1], [-36, -31, 40, 18, 36], [-44, 13, -8], [-16, -13, 24, 32, 33], [3, 13], [40, 32]]

SOLUTION: [-864, 27648, 24, -228, 14, 0, -933120, 352, -12288, 0, 1280]

PROBLEM: [[-9, 15, -43], [30, -6, -8, 3], [0, -21], [38, -17, 16], [31, -45, 32], [-43, -36], [42, 49, -41, 44], [-12, -28, -5]]

SOLUTION:
[0, 1440, 0, 608, 32, -36, 1848, 336]
