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: [[-38, 35, 29, 26], [-38, -24, -14, -40, -26], [-41, 46, -12, -6], [10, 31, -38, -8, -28], [-25, 10, -27, -1], [-14, 39, -50, -30], [-17, -8], [-41, 49, 18, -25, 44], [-26, 46, -9, -19, -17]]

SOLUTION: [-988, -13278720, 3312, -85120, 10, -21000, -8, 792, -1196]

PROBLEM: [[-25, 23], [40, 10, 28, -5, 49], [21, 11]]

SOLUTION: [0, 11200, 0]

PROBLEM: [[-8, 50, -24, -47], [11, -11, 33], [-43, 24], [17, -28, -25], [-27, -38, 46, 34, 48], [29, 8, -39, -48]]

SOLUTION:
[9600, 0, 24, -28, -2852736, -384]
