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: [[-49, 2, 10], [-8, 18, -35], [0, 21, -23, -40], [10, 27]]

SOLUTION: [20, -144, 0, 10]

PROBLEM: [[40, -27, 50, -24], [17, 8, -49], [-10, 48, -1, 28, -36], [13, -42], [-27, -11, -45], [-24, -11], [14, -10, -33, -1, -26]]

SOLUTION: [-48000, 8, 483840, -42, 0, -24, 3640]

PROBLEM: [[9, -30, -31, -47], [14, -2], [-23, 45, 11], [9, 25, 39, 31, -14], [-34, 48, -12, -5, -32], [-40, -25, -23, -6, -28], [32, 45, 42, 42], [-32, 6, -17, 44, 39], [11, 29], [44, -31, -39], [-32, 6], [-39, -10]]

SOLUTION:
[-30, -28, 0, -14, -626688, -6720, 56448, -8448, 0, 44, -192, -10]
