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: [[23, -22, 8], [-9, 49, -1], [-26, 18, -19], [6, 26, 30, 39, -32]]

SOLUTION: [-176, 0, -468, -149760]

PROBLEM: [[33, 37], [34, 43, -49, 9], [27, 15], [46, 38, 47, 41], [-19, -37, 30, -18, 33], [-15, -14, 17]]

SOLUTION: [0, 34, 0, 1748, -540, -14]

PROBLEM: [[-35, 29, 41], [40, 40, 18, 2], [-15, -50], [36, 29, 7], [14, 0, -7], [-17, 18], [-36, 16]]

SOLUTION:
[0, 57600, -50, 36, 0, 18, -576]
