By Using Static variables any memory issue?

Answer 1

Ravi Vardhan AAdhf static variables has the same method of memory allocation they don't differ in memory allocation as far as I know...
It saves memory by not creating separate variable for each recursive call or different function call.
Thus there's a high chance that recursion might make your program run out of memory, if there's a lot of memory allocation in the method.

Ig I have missed many points.. you can see this one..
