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: [[0, -14, 2, 35, -25], [-21, -38, 22, -39, 3], [-13, -47, 34, 50]]

SOLUTION: [0, -836, 1700]

PROBLEM: [[19, 14], [26, 35, 27], [-46, 18, 1], [-9, 3, 17, -13, 30], [46, 28, -20, 22, -42]]

SOLUTION: [14, 26, -828, 30, 23802240]
