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: [[-3, 48], [-4, -24, 6, 12, -47], [-39, 18], [48, 29, 28], [0, -9, -13, -2], [6, -9, 1, 47], [44, 40, 17], [-32, -22, -31, -10], [41, 32, -37, 20, -21], [3, -37, -48, -1, -28], [6, 41], [4, 21, 45, 41, -32], [-44, 39, -11], [43, -36, 17], [1, -15, -34, -31, 46]]

SOLUTION: [48, 6912, 18, 1344, 0, 6, 1760, -7040, 640, 1344, 6, -128, -44, -36, -1564]

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

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

PROBLEM: [[-8, -34, -31, -47], [-36, -48, -24, 49], [43, -7, -43, -30, 43], [-36, -25, -39, 8, -21], [-49, 32, 47, -47, 9], [48, 43, 22], [12, 45, -35], [-45, -17, 5, 19], [-27, 20], [14, -15, -14], [-3, -24, 36, 0, 9], [50, 34, 33], [36, 33, -41, -39, 20]]

SOLUTION:
[272, -41472, -30, -288, 32, 1056, 12, 0, 20, -196, 0, 1700, 720]
