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: [[2, 44, -17], [37, -39, -23, -31, 24], [41, 18, -46, 30, -29], [-10, 22, 24, 14], [5, -43, 17], [4, 36, -34, -13, -18]]

SOLUTION: [88, 24, -24840, -73920, 0, 88128]

PROBLEM: [[-20, -21], [49, 15, 47, -50, 14], [1, -3, 31], [41, -23], [-38, -35, 38, 17], [17, -22], [-35, 2, 46, 14], [-10, -11], [14, -44, 38, -35, 0], [-47, -22]]

SOLUTION: [-20, -700, 0, 0, -1444, -22, 1288, -10, 0, -22]

PROBLEM: [[3, -1, -32, 6], [-2, 16, 17], [-12, 4, -29, -50, 16], [6, -34, -9, 13], [38, -47, -15], [-18, -13, -19], [-46, -2], [35, -16, 25], [33, 46, -45, -2, 4], [-28, 17, -15, 6, 18], [-9, -50], [-14, 30, 1, 40, -43], [-43, -21, -20, -25, -16], [-20, 16], [-22, 35, 37, 1]]

SOLUTION:
[-192, -32, 38400, -204, 38, -18, 92, -16, -368, -3024, -50, -16800, 320, -320, -22]
