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: [[23, 12, 35, -33], [6, -37, -14, 23], [-25, -14], [12, -50, 11, -38, 36]]

SOLUTION: [12, -84, -14, 820800]

PROBLEM: [[-39, 1], [-36, 36, -8, 24], [-46, 39, 9], [18, 45, 23, -43], [-43, 44, 43, -35, 10], [48, 44], [20, 47, -38], [-7, 17, 9, 6], [20, 35], [8, 23, -24, -46], [32, 32, 6], [23, 17], [12, 46, -42, -6], [-27, -49, -31]]

SOLUTION: [0, 248832, -46, 18, 440, 2112, -760, 6, 20, 8832, 6144, 0, 139104, 0]

PROBLEM: [[9, 40, -23], [2, -7], [-22, -20, -21], [34, 50, -40, -11, 21], [20, -18, 34, 17, 49], [-49, 46, -4, 13], [24, -45, -42, -3], [33, -37, -27, -12, -32], [-39, 14, 43], [43, -10, -21], [3, -22, -38], [-19, -19, -38], [-44, 48], [-6, -30, 34]]

SOLUTION:
