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, 22, -22, -41], [-27, -30, 35, -49], [44, 10], [30, 5, -47, 37], [25, -15, 48], [-42, -21], [41, -48], [19, 18, -10, -4]]

SOLUTION: [-12584, -30, 440, 30, 48, -42, -48, 720]

PROBLEM: [[-46, -27], [47, -29, 30, -50], [-28, -47, -20, 28], [45, 10, 32, -11, -42], [26, -10, 17], [-31, -29, -30, 11, -49], [36, 10, -12, -34, 30], [-10, 30, -18, 23], [-36, 50, -14, 0], [-8, -44, 40, -45], [41, -16, 30], [38, 38, -46, 18, 31], [29, 43, 5, -42], [48, -28]]
