So, I am new to programming in c++ and i came across this question where i need to calculate pow(2,n)/2 where n>64 ?
i tried using unsigned long long int but as the limit of the c++ is only 2^64. So is there any method to calculate this.
Edit:
1 < n < 10^5
The result of the expression is used in further calculation
The question is asked on online platform.So, i cant use libraries like gmp to handle large …
