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: [[40, -27, 50, -24], [17, 8, -49], [-10, 48, -1, 28, -36], [13, -42], [-27, -11, -45], [-24, -11], [14, -10, -33, -1, -26]]

SOLUTION: [-48000, 8, 483840, -42, 0, -24, 3640]

PROBLEM: [[20, 4], [11, 29, 18, -6], [34, -10, 17, -39, -33], [-22, 44], [1, 30, 25, -45, 50], [-7, -4, 28], [-29, 44, -1, -11], [-21, -2, 12], [-38, 10, -38, -34, 0]]

SOLUTION:
[80, -108, -340, -968, 1500, -112, 44, -24, 0]
