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: [[8, 39, -6, -41], [-24, -14, -29, -22], [36, 41, 42, -29], [2, -28]]

SOLUTION: [-48, -7392, 1512, -56]

PROBLEM: [[-37, 49, -21, 27, -34], [13, 0, -18, 27, -10], [-41, 9], [26, -13, -22, 3, -12], [-17, -43, 28, -31, -41], [-33, 1, -40, -13], [37, 30, 4, -18], [-24, -43], [-10, -49, 16], [31, -32], [-5, -38, 38, 5], [-40, -30]]

SOLUTION: [-34, 0, 0, 6864, 28, -40, -2160, -24, -160, -32, -1444, 1200]

PROBLEM: [[-23, 22], [-17, 31, -6, -50], [43, 37, 1, -39, -16], [31, -37, 10], [-32, 12, -42, -38, 8], [18, -42, 15], [-24, -31, -47], [40, 18, -5, 30], [-50, 18, 44, 38, 8], [5, -6, -40], [31, 19, 9, 35], [-12, 43, -3, -13], [-33, 22, 44, 8, -22], [-48, 28, 3, 16], [-45, -46]]
