C++23 introduces new features enumerate and ranges
Optimizing performance for a hot function involves the bulk of the time spent within internal loops. AI suggested using enumerate and ranges, so I consulted some related documentation.
The main content of the article was generated by AI, and I tested the code and added some supplementary explanations. Online Compiler – testing C++ code inevitably involves our old friend.
On gcc13, traditional for loops were slightly faster than std::views::enumerate, which is negligible in practice.
