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: [[-29, 9, -38, 26], [39, 14, -7, -24, 15], [15, 26, -33], [-12, -30, 44, -27, 17], [-26, -26, 20], [-29, 12, 34, -14, 27], [-40, 39], [50, 9, -48, 8, 19], [-45, -37, -15, -47]]

SOLUTION: [-988, -336, 26, 15840, 13520, -5712, -40, -19200, 0]

PROBLEM: [[31, -19, 33], [16, 10], [-32, -36, -23]]

SOLUTION: [0, 160, 1152]

PROBLEM: [[-25, 40], [50, -1, 13, -26], [43, 22, -29], [-35, 24, -7, -2], [-18, 8, -14, 43, 23], [-22, 43, -26]]

SOLUTION:
[40, -1300, 22, -48, 2016, 572]
