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: [[16, -21, -6, 27], [11, -14, -41], [-43, 26, -12, 9, 47], [-5, -29, -21, 16], [38, 17], [-24, 22, 34, -5], [47, -31, 41, 38], [-35, -46, 23, -29], [37, -11], [-50, 11, 28], [11, -17], [-15, 6], [-24, 11]]

SOLUTION: [-96, -14, -312, 16, 38, -17952, 38, -46, 0, -1400, 0, 6, -24]

PROBLEM: [[28, 49], [-9, -22, 27, -43], [-20, 15, -6, 31, -14]]

SOLUTION: [28, -22, -1680]

PROBLEM: [[-27, 46, 29], [-42, -26, 31], [18, -39, -31], [49, 40, 35], [30, 43, 5, -40], [-1, -24], [-33, -43, -7, 32, -39], [-37, 46], [-19, 13, 9, -46], [-48, 18, 50, 37], [49, -12, 24, -27, -10], [-35, 37, -39, 6], [14, -30, -1], [39, 4], [-50, -39, 15, 14, 27]]

SOLUTION:
[46, 1092, 18, 40, -1200, -24, 32, 46, -46, -43200, 2880, 6, -420, 4, -700]
