I am doing a task in which there are 300000(3e5) queries, after using assertion, I came to know only 5000 queries are left. I want to know if there are any other some c++ optimizations to squeeze my solution to AC.

I am currently using:
1. scanf
2. printf
3. #pragma GCC target ("avx2") #pragma GCC optimization ("O3") #pragma GCC optimization ("unroll-loops")
4. Fast I/O
