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: [[-25, 34, 42, 30], [-14, 12], [20, -12, -43, 33], [36, 5], [-11, 34, -44, 2, 20], [-49, 45, 19, -45], [-11, -47, -35, 26], [29, 45, 9, -39, 26], [-26, 29, 7]]

SOLUTION: [42840, -168, -240, 36, -59840, 0, 26, 26, -26]

PROBLEM: [[-46, 5], [9, 48, 17], [-6, -3, -26]]

SOLUTION: [-46, 48, 156]

PROBLEM: [[-12, -50, -16], [-17, 9, -4, -17], [34, -14, -8, 41, 20], [8, -45, 7], [-19, 0, -8, -6], [20, -4, -24], [11, -8, 16, -33, -11], [43, -46], [-22, 18, 50], [19, 9, -20, -19], [-16, -34, 3], [-27, 42, -19, 21], [16, -12]]

SOLUTION:
[-9600, -4, 76160, 8, 0, 1920, -128, -46, -19800, -20, 544, 42, -192]
