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: [[26, 24, -42, 4, -8], [50, 25, 3, -46, -27], [37, 47, -10, -1], [-39, 1], [-31, 10, 29, -14], [7, -21, -18], [7, -19, -17, -16], [-9, -44, 40]]

SOLUTION: [838656, -2300, -10, 0, -140, -18, -16, -1760]

PROBLEM: [[-14, -20, -45, 6, -16], [-26, -44], [-2, -47]]

SOLUTION: [-26880, 1144, -2]

PROBLEM: [[-10, -31, -1], [-36, -31, 4, 19, 41], [23, -15], [27, -14, -45], [14, 33], [40, 35], [9, 20, -22], [-21, -12, -36, 49, -36], [-46, 5, 28], [48, 44, 11, -43], [-46, 1, 38, -7], [-28, 46, 19, 1], [-32, -30, 37], [5, 43, 21], [-38, -49, 43, -28]]

SOLUTION:
[-10, -144, 0, -14, 14, 40, -440, -15552, -1288, 2112, -1748, -1288, 960, 0, 1064]
