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, 45], [42, -49, 7, 7], [-24, 19, -12, 21, 21], [-29, 39, 39], [-18, 21, -45, -25, 50], [-36, -39, 39, -10], [45, 20, -35, 27], [-18, 20, -45, -39, 50], [-2, 20], [-13, 20, -32], [26, -25, -8]]

SOLUTION: [-10, 42, 288, 0, -900, 360, 20, -18000, -40, -640, -208]

PROBLEM: [[-7, 46, -33], [-5, 11, 34, -34, 28], [-24, 20, 33, -26, -49], [-35, 12, -50, 42, 26], [40, 20], [-21, 11], [39, -29, -36], [-17, 2], [36, 48, -13, 10, -48], [-29, -44], [-40, -39]]
