|_| |_| This C++ library provides an efficient HashMap implementation designed to offer higher efficiency than the standard library std::unordered_map when dealing with large datasets, while being on par with the efficiency of std::map. Additionally, the library can be easily included by simply importing the header file, without the need for complex installation or configuration processes.
- High Performance: The HashMap implementation is optimized to maintain high efficiency when processing large-scale data.
- Simple Inclusion: Just include the header file, no need for cumbersome setup or configuration.
