Big Integer Library (C++) Features : Arithematic Operations : Addition + Division / Modulo % Multiplication * Subtraction - Math Functions Factorial(n) Fibonacci(n) Gcd(a, b) Lcm(a, b) Pow(x, n) How to Use : Step 1 To Make Submissions on Online Judges(CodeChef, CodeForces, etc.) Copy the code from bigint.h and paste it in your solution file. To Use it locally Clone this repository and place bigint.h in same path as of your project. Just add these two lines at the start of your file #include "bigint.h" using namespace MathFunctions; Step 2 Now we can use all of the above features for Big Integers Declarations and Initializations Arithematic Operations Math Functions
