WebWhile calculating (ab) % m, we can simply take modulo at each multiplication step. Below is a code Modular Exponentiation (Power in Modular Arithmetic) in C++, #include using namespace std; int powerMod(int a, int b, int m) { int res = 1; a = a % m; while(b>0) { if(b&1) res = (res * a) % m; a = a * a; b = b >> 1; } return res; } WebIt will work like this: F (2,2)=2*F (2,1) Again it will call itself, F (2,1)=2*F (2,0) Now the base case is reached as b=0, it will return 1, then F (2,1)=2*1=2 and F (2,2)=2*2=4, which is our required answer. Let us implement the above idea in our code. Program to calculate power of a number in C++ using Recursion Cpp source code:
Web21 feb. 2024 · The mathematical expression to calculate the power of any number is as follows: (a b) or (a ^ b); where a is called the base and b is called the power or exponent. … WebIn general if you have two co prime integers m and n, then m^p modulo n = m^ (p%f (n)) modulo n, where f (n) is Euler totient function This.
