Advantages:
Through Recursion one can Solve problems in easy way while
its iterative solution is very big and complex.
Ex : tower of Hanoi
You reduce size of the code when you use recursive call.
Disadvantages :
Recursive solution is always logical and it is very
difficult to trace.(debug and understand)
Before each recursive calls current values of the varibles
in the function is stored in the PCB, ie process control
block and this PCB is pushed in the OS Stack.
So sometimes alot of free memory is require for recursive
solutions.
Remember : whatever could be done through recursion could be
done through iterative way but reverse is not true.
