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: [[10, -9, 27], [-18, -2, 2], [-44, 26, -34], [29, -2], [-49, -23, 8], [7, -49, -44], [-31, 2, -4, -35, 17], [-40, -12, -31, 19, 29]]

SOLUTION: [10, 72, 38896, -2, 8, -44, -8, 480]

PROBLEM: [[-26, -3, -47, -36, -22], [-7, 31, 10, 47, -8], [24, -7, -17], [-28, 11, 19, 20, -32], [-12, 37, -14], [30, 30, 13, 17], [34, -19], [15, -47, -24], [-30, 23], [-41, 8, 14], [-12, 20, -41], [45, -38, -25], [44, 42, 28, -29, 27], [20, 9, -18], [14, -5, -6, -29]]
