# Sorting Algorithms
[](https://github.com/JuliaLang/SortingAlgorithms.jl/actions?query=workflow%3ACI+branch%3Amaster)

The `SortingAlgorithms` package provides four sorting algorithms that can be used with Julia's [standard sorting API](https://docs.julialang.org/en/v1/base/sort/):
- [HeapSort] – an unstable, general purpose, in-place, O(n log n) comparison sort that works by heapifying an array and repeatedly taking the maximal element from the heap.
- [TimSort] – a stable, general purpose, hybrid, O(n log n) comparison sort that adapts to different common patterns of partially ordered input data.
- [CombSort] – an unstable, general purpose, in-place, O(n log n) comparison sort with O(n^2) pathological cases that can attain good efficiency through SIMD instructions and instruction level parallelism on modern hardware.
- [PagedMergeSort] – a stable, general purpose, O(n log n) time and O(sqrt n) space comparison sort.

## Usage
```jl
julia> using SortingAlgorithms
julia> words = map(chomp,[readlines(open("/usr/share/dict/words"))...])
235886-element Array{ASCIIString,1}:
"A"
"a"
"aa"
⋮
"zythum"
"Zyzomys"
"Zyzzogeton"
julia> sort!(words, alg=TimSort)
235886-element Array{ASCIIString,1}:
"A"
"Aani"
"Aaron"
⋮
"zymurgy"
"zythem"
"zythum"
julia> sort!(words, alg=TimSort, by=length)
235886-element Array{ASCIIString,1}:
"A"
"B"
"C"
⋮
"scientificophilosophical"
"tetraiodophenolphthalein"
"thyroparathyroidectomize"
julia> sort!(words, alg=HeapSort)
235886-element Array{ASCIIString,1}:
"A"
"Aani"
"Aaron"
⋮
"zymurgy"
"zythem"
"zythum"
julia> sort!(words, alg=HeapSort, by=length)
235886-element Array{ASCIIString,1}:
"L"
"p"
"U"
⋮
"scientificophilosophical"
"tetraiodophenolphthalein"
"thyroparathyroidectomize"
julia> sort!(randn(1000), alg=CombSort)
1000-element Array{Float64,1}:
-2.86255
-2.72041
-2.58234
⋮
