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: [[32, 37], [-27, -1, 12], [-11, -18], [-45, 39, -21], [-22, 23], [-32, 44, 48, 18, 34], [-29, 30, 34], [33, -20], [7, -43, 23, -7, 4], [-2, -18, 2, 43], [26, 30, -33], [-30, 19, -31, -42], [17, 1, -4], [-23, 40, -22, 42, 4]]

SOLUTION: [32, 12, -18, 0, -22, -41361408, 1020, -20, 4, 72, 780, 1260, -4, -147840]

PROBLEM: [[19, 14], [26, 35, 27], [-46, 18, 1], [-9, 3, 17, -13, 30], [46, 28, -20, 22, -42]]

SOLUTION: [14, 26, -828, 30, 23802240]

PROBLEM: [[0, 31, -41, 31], [-14, 11, -21], [26, -39]]

SOLUTION:
[0, -14, 26]
