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: [[-34, -24, 27, 14, -14], [-27, -23, 2, 30], [-31, -17, -19, 42], [-15, 46], [2, -26, -43, 6], [-17, 31, 6], [-22, 38, -11], [-39, -23], [-37, -20, -27, -17], [14, -22, -32], [30, -11], [-22, -42, -26, 20, -38], [44, 30, -20], [49, 15], [3, 42, 29, 28, 26]]

SOLUTION: [-159936, 60, 42, 46, -312, 6, -836, 0, -20, 9856, 30, 18258240, -26400, 0, 30576]

PROBLEM: [[25, 34], [43, 2, 40, -25, -45], [16, -49, 40, 18]]

SOLUTION: [34, 80, 11520]

PROBLEM: [[13, 13, -11], [-14, -34, -9], [19, 42, 29, -32], [-49, 20, -28, 40], [31, -20, 5, 15], [35, 14], [39, -32, 21], [44, -30, -15, 50], [48, 7], [-46, 28, -14, -4], [6, -14, -50, -48], [14, 2, -34, 31]]

SOLUTION:
[0, 476, -1344, -22400, -20, 14, -32, -66000, 48, -72128, -201600, -952]
