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: [[14, -2, -10, 21], [29, 11], [13, -8, -29, -38, -17], [13, -38], [-11, 47], [-37, -20, 12, 17, 26], [-30, 2, -44], [47, 7, -4, -13, 14], [22, -27, 5, 4, -34], [31, -10, -18, -41, -32], [19, 46, 36], [19, -43, 2], [0, -27]]
