WebExponentiation is a very common part of mathematics, and it’s involved in many programming puzzles. If you don’t have a function already implemented for you, a simple algorithm to compute a^b (a to the power of b) would be: int expo (int a, int b) { int result = 1; while (b>0) { result *= a; b--; } return result; } WebFast Modular Exponentiation. Modular exponentiation is used in public key cryptography. It involves computing b to the power e (mod m):. c ← b e (mod m). You could brute-force this problem by multiplying b by itself e - 1 times, but it is important to have fast (efficient) algorithms for this process..
