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: [[-43, 5], [2, 43], [7, -2, 42], [-20, -43, 40]]

SOLUTION: [0, 2, -84, -800]

PROBLEM: [[-29, 37, -20], [13, 17, 13, -33, 2], [-8, 34, -44]]

SOLUTION: [-20, 2, 11968]

PROBLEM: [[-28, -11], [38, -37, -34], [-47, 45, 49], [9, 16, 19], [50, 31, 22, 10], [-38, -14, -34, 3], [34, 25], [9, 26, 22], [-10, 24, -13, -17], [45, -38, -4], [23, 11, 37, -38], [-46, 20, -49, 1, -16], [37, 11, 32, -7], [-18, 45, -4, 48, -22]]
