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: [[-16, 2, -49, -3, 6], [-20, 3], [38, 15, -34, 27, 37], [23, -3, -3], [-46, -36, -36], [49, -45, 38, 37, -35], [38, 21, -4], [3, -38], [28, 37, 45], [0, 5], [6, 42, -24], [48, -45]]

SOLUTION: [-192, -20, -1292, 0, -59616, 38, -152, -38, 28, 0, -6048, 48]

PROBLEM: [[46, 20, -29], [-11, 14], [-21, 9, -16, -22, 13], [46, -5], [-6, -35], [-48, 45, -25], [-33, 3, -41, 12, -45], [-21, 16, -8, -27], [14, 49], [40, -3]]

SOLUTION: [920, 14, 352, 46, -6, -48, 12, -128, 14, 40]

PROBLEM: [[1, 22, 47, -2], [42, 11], [-8, -6, 10, -11, -22], [43, -50], [18, 39, 45, 27], [39, 13], [-18, -47, -14, -47], [-5, 2], [-39, -31, -2, -15], [-29, 37, -36, 46], [19, -43], [49, 37], [-16, 21, 16, 12], [-5, -45, -28, 4]]

SOLUTION:
[-44, 42, -10560, -50, 18, 0, 252, 2, -2, -1656, 0, 0, -3072, -112]
