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: [[0, 43, 10, -26], [-28, 12, -40, 29, 11], [-5, -26, 28, -17]]

SOLUTION: [0, 13440, -728]

PROBLEM: [[4, 39], [-49, -6, 5, 41, 25], [-40, -45, -33], [28, -23, 45], [8, -32], [-8, -43, -4, -24], [-19, -43, 6, 2, -28], [35, -28, 37, 21], [45, 41], [-34, 27, 25, 5], [-23, -1]]

SOLUTION: [4, -6, -40, 28, -256, -768, -336, -28, 0, -34, 0]

PROBLEM: [[50, 12], [-22, -36, -46], [-45, -20, 6], [-13, 11, -47, -16, 28], [5, 33, 5, 12], [-42, -42], [44, -20, 6, -36], [-32, 19, -9, 14, -26], [18, 19, 41], [-41, -48, -28, 31, 4]]

SOLUTION:
[600, -36432, -120, -448, 12, 1764, 190080, 11648, 18, 5376]
