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: [[35, 17, 7, -41, 22], [33, -17], [-50, 31]]

SOLUTION: [22, 0, -50]

PROBLEM: [[-27, -15, -29], [-30, 44, 42, -2, 31], [-20, -21], [49, 36, 49], [-36, -45, 44, -47, -34], [41, 37, -29, 23, -42], [25, 46, -12, 49, -49], [-22, 1], [-3, 21, -20, -48], [-39, -9, 26, 22]]

SOLUTION: [0, 110880, -20, 36, 53856, -42, -552, -22, 960, 572]

PROBLEM: [[-45, -47], [50, -6, -22, -9, 37], [-31, 35, -3], [4, -8], [-22, -50, -19, -36], [-15, 29], [-22, -49, -16, -38, 43], [35, 26, -36], [-14, 17, 11, 39], [20, 14, -40, -26], [-5, -40, 28, 31], [41, -50, 49], [6, -17, -6, -28, 15]]

SOLUTION:
[0, 6600, 0, -32, -39600, 0, -13376, -936, -14, 291200, -1120, -50, 1008]
