How to Quickly Compute Large Modular Exponentiation Using Recursion

How to calculate a power b modulus n i.e (a ^ b mod n)

this is called modular origami, where you fold many pieces of paper and combine them at the end! When you think of origami, you probably think of one piece of paper folded over and over again into some crazy final form - this kind of origami can be magnificent but very complicated to fold.
