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: [[4, 48, 11, -29, -42], [2, -23, -18], [-7, -27], [-43, -18, -34, 16]]

SOLUTION: [-8064, -36, 0, 9792]

PROBLEM: [[-33, 49, 15, 3], [49, -36, -17], [-5, 18, -4], [39, -24, 1, 49, -14]]

SOLUTION: [0, -36, -72, 336]

PROBLEM: [[43, -48, 35, 6, -50], [37, -6], [36, -9], [12, 32], [-18, -36, -47, -29], [-24, 16, -16, -43, -21], [-47, -41, -29, 9], [-47, -32, -30], [31, -31, -24, 7, 23], [5, -26, -45, 30], [-21, -25], [-23, 42, -43]]

SOLUTION:
[14400, -6, 36, 384, 648, 6144, 0, 960, -24, -780, 0, 42]
