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: [[-49, -13, 16, -46, -12], [50, 8, 14], [-36, 30], [-35, -39, 43], [-28, 27, -18]]

SOLUTION: [8832, 5600, -1080, 0, 504]

PROBLEM: [[-24, 45, -3], [-35, 26, -34, -49], [23, -1, -24, -37, -15], [27, -21, 27, 34, 15], [-41, 4, -11], [2, 6, 33, -31], [41, 47, 46, -45], [16, -11, -42, 5, 34], [49, 10, 3], [30, 9, -18, 7, -4], [11, 21], [16, -25, -36], [7, -2, -12, -14], [1, -46, -4, 21, -43], [12, -15]]
