Use long long. In the worst case, all the functions are from 1 to n and each query can have a maximum answer of 10^3 (1…n) * 10^9 (each element) * 10^3 (functions 1…n). Unsigned long isn’t sufficient to hold 10^15.

use long long int… python does not care about data types. It can handle bigger calculations with int datatype.
But C++ have data type limits defined.
