Explain the difference betweenat()and the implementation of the operator[]. Wy did you have to overload one and not the other? Hint: You will likely only need to read the header comments to do this Notes: recall that operator[], which you will implement, does not throw exceptions, if ...
A simple one header hashmap implementation for C/C++.UsageJust #include "hashmap.h" in your code!The current supported compilers are gcc, clang and msvc.The current supported platforms are Linux, macOS and Windows.Fundamental DesignThe hashmap is made to work with any arbitrary data keys - ...
hashing, where values are stored directly into a memory array, avoiding memory indirections. By using parallel SSE2 instructions, these hashmaps are able to look up items by checking 16 slots in parallel, allowing the implementation to remain fast even when the table is filled up to 87.5% ...
