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: [[-13, 26, -11, -16, -33], [41, -49], [-31, 3], [31, -13, -31, 13, 37], [10, -42, 33]]

SOLUTION: [-416, 0, 0, 0, -420]

PROBLEM: [[2, 31, 49], [7, -48], [-5, 16, 2, 28]]

SOLUTION: [2, -48, 896]

PROBLEM: [[-37, 50], [32, 36, 11], [-23, -41], [1, -27], [29, -16, 34], [2, -8, 28, 34, -20], [-48, 18, -47, -15], [-38, 23, -5, -24, 47], [-26, -42, 14, 8, 8], [47, -45], [13, -28, 16], [-40, -41, -36, -19, -26], [-7, 17, 39, -8, 33], [21, -35]]

SOLUTION:
[50, 1152, 0, 0, -544, 304640, -864, 912, 978432, 0, -448, -37440, -8, 0]
