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: [[27, 25, -36, 12, 17], [41, -49, 23, 13, 31], [37, 19, 34, 34, 48], [24, -41, 29, -23], [39, -41, -9, 33, -14], [41, 40, -31, 41], [20, -12, 21], [12, 13, -16, -11, -44], [-15, 41, 6, 0], [-8, 31], [3, 25, -15, -46]]

SOLUTION: [-432, 0, 55488, 24, -14, 40, -240, 8448, 0, -8, -46]

PROBLEM: [[18, -11, -13], [-20, -21, 26], [40, 6, 3]]

SOLUTION: [18, -520, 240]

PROBLEM: [[-37, -36, 0, 5], [-23, -43, -47], [0, -40, -16, 6], [44, 25], [-34, 50], [15, -17], [-27, 18]]

SOLUTION:
[0, 0, 0, 44, -1700, 0, 18]
