Usage of Dynamic
-----------------
I have used Dynamic instead of object. If I use object then I have to write typecasting statements when reading the integer values in the array.
Readability is good with dynamic.

Usage of Queue
---------------
Since we are reading the elements in the FIFO order, I used Queue rather than List.
