I have noticed that whenever I write a program in C/C++ which involves modulo operated long long or unsigned integers, I end up getting WA. But when I submit the same code in python I get AC. Does modulo work differently with unsigned and long long ints ?

Hey, well i don’t know case of python, but there is problem with your code in c/c++, when you do something like (sum - term)%mod, if sum -term is negative, you’ll get different answer, maybe in python they convert the expression to positive and then take modular, if we do it like this, (sum + mod - term)%mod, there won’t be any problem in c/c++
check this , AC with your solution after adding mod in expression where minus in used.
