How to deal with large values in C++

can anybody tell me how to deal with large values in c++ that even unsigned long long int can’t handle because, if i code for the same problem with same logic and algorithm in python it somehow runs most of the times.

I normally use a string to operate on very large values. You can read this article for more details.

no but if i have to do computations with these values or after some sort of computations you are getting these large values as a result then ?

search Boost libraries in C++. You will get your answer. :slight_smile:

but it is more necessary that online judges supports boost libraries or not.

they support. :slight_smile: go for it

If you really need it, you can use a bigint class written by yourself or someone else like this. Most of the times, the problems can be solved without using such large numbers.

This kind of problems are rare.
But If you really require it use array/string.
Simulate the process which we learned in school.

see this question and code…

Libraries use better algorithm for multiplication like karatsuba algo
