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: [[0, -44, -42], [-1, -2], [-40, 23, 19, -23]]

SOLUTION: [0, -2, -40]

PROBLEM: [[6, -17, 19, 42], [40, -6, 30, -4, -13], [-3, -42], [37, 39, 26], [-7, -23, 16, -15, 42]]

SOLUTION: [252, 28800, -42, 26, 672]

PROBLEM: [[-5, 5, 35], [50, -49, 9], [14, -11, 7, 7], [21, 42, -12, -44], [-36, 27, 32], [23, 17, 1, -15], [-19, 31, 3, -46], [-26, 13, 27, -49, -10], [-35, -33, 23], [35, 41], [-5, 32, 50], [29, 45, 47, -34]]

SOLUTION:
[0, 50, 14, 22176, -1152, 0, -46, 260, 0, 0, 1600, -34]
