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: [[-2, -49, -16], [37, -24, 11], [17, 33], [16, -15, -5], [4, 19, -46]]

SOLUTION: [32, -24, 0, 16, -184]

PROBLEM: [[-27, 32, 14], [-5, 39, -28], [-41, -44], [-4, -17, 33], [-32, -11, -3, 3], [-14, -48], [12, -15, 19, 41, 34], [-43, -36, 39], [-44, -26], [-49, 30], [7, 37, -28, 35, -19], [-20, 6, -36, -31], [10, 24, -17]]

SOLUTION: [448, -28, -44, -4, -32, 672, 408, -36, 1144, 30, -28, 4320, 240]

PROBLEM: [[-1, -22], [-24, 2, 4, -6, -37], [-9, -19, 16, -14, 43], [7, -41, 48, -42], [-8, -15, -5, -4, -10], [8, 0, 22], [49, 14, 29], [28, 20, 11, -14, -44], [-28, 37, -26, 21, -32], [1, 11, -1], [15, -23, -39, -3], [-29, 35, 16, -9]]

SOLUTION:
[-22, 1152, -224, -2016, -320, 0, 14, 344960, -23296, 0, 0, 16]
