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: [[32, -19], [-27, 9, 45, 11], [-24, 21, -22, -16], [50, 7], [-31, 10], [24, 14, -29], [-39, 37, 16], [-5, -7]]

SOLUTION: [32, 0, -8448, 50, 10, 336, 16, 0]

PROBLEM: [[18, 40, 13, -2, -25], [7, 13, -41, 11, -32], [6, 14], [40, 41], [22, 46, 14, 45, 2], [35, 9, -16], [48, 41, 47, -22, 25], [30, 22, 44, -33], [-34, -37, 3, -27], [44, -1, -35, -22], [1, 1, 29], [-49, 50, 40], [-14, -17, 6]]

SOLUTION: [-1440, -32, 84, 40, 28336, -16, -1056, 29040, -34, -968, 0, 2000, -84]

PROBLEM: [[30, 9, 30, -44, -49], [-37, -44, 44, -8], [50, 23, -24, -11], [16, -18, 24, 37], [-40, -15, -35, -9, -10], [-18, -43, -17, 42, 36], [9, -25, -27, -7, -2], [43, 21], [28, -37, 27], [18, 21], [50, 25]]

SOLUTION:
[-39600, 15488, -1200, -6912, 400, -27216, -2, 0, 28, 18, 50]
