Final Thoughts

Was the MP Board 10th-grade English paper really leaked? Will the exam be re-examined? The above line is a C code which I downloaded. It has a part 1ULL. First I thought it was a mistake but the code compiles and works well. Can anyone please explain me what is that thing mean?

You cannot use ULL after variables. It is a suffix for integer literals. You should use ULL after those integer literals that you wish to be of type unsigned long long because that's what the suffix does. All integer types have an upper (as well as lower) limit.
