# Overview

This is a highly-optimized sorting library, compatible with C++03

Timsort: Tim Peter's [original implementation](https://github.com/python/cpython/blob/master/Objects/listsort.txt)

# Usage

Here is the demo, or you can try [demo.cpp]

```c
#include "sortlib.hpp"
#include <cstdlib>

int main(void)
{
    std::vector<int> arr(100);

for (size_t i = 0; i < arr.size(); i++)
    {
        arr[i] = rand();
    }

baobao::sort::tim_sort(arr.begin(), arr.end());
    return 0;
}
```

Call it like STL as well

### Note
`merge_sort_s`, `merge_sort_buffer_s`, `tim_sort_s` is the safe copy version if you overload operator `=` and do something different

# Performance

Run the code [sorttest.cpp], it will output the result

Build with `g++ -std=c++03 -O3 sorttest.cpp` on Centos 7 x64, gcc version is 8.3.1

Functions name with `bao_` perfix are in `sortlib.hpp` header  
Functions name with `grail_` perfix are in `grailsort.hpp` header  
`std_qsort` is the `qsort` function in `stdlib.h` header

The x-axis is `log2(length)`

The y-axis is `time / length * 1000000`
