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: [[-40, 39, 47], [32, -22, 29, 4], [-27, -11], [42, 26, 20, -12, 28], [-19, 46, 1], [-24, -38], [-32, 34, -44], [-1, 49], [-6, 42, 16], [2, 42, -29, 7, 22], [8, -47, -42, -20]]

SOLUTION: [-40, -2816, 0, -7338240, 46, 912, 47872, 0, -4032, 1848, 6720]

PROBLEM: [[0, -27, -21], [-21, -13, -22, 48, 22], [21, 30, -19, -47, 47], [37, 15, -8, 0, 20], [20, -31, -8, 19, 32]]

SOLUTION: [0, -23232, 30, 0, -5120]

PROBLEM: [[-42, 35, 7, 0], [-29, 28, -32], [-17, -21, 6], [-9, -13, -15], [-12, 27, 18, -16], [-16, 23, 21], [49, -33, 7, -16], [-10, 11, -25, 33], [50, -10], [-8, -16, 40, -43], [-9, -33, -48, -34, -41]]

SOLUTION:
[0, -896, 6, 0, 3456, -16, -16, -10, -500, 5120, 1632]
