sort

A Multi-Pivot Quicksort implementation in Go. The algorithm is taken from the paper Multi-Pivot Quicksort: Theory and Experiments

Usage

This package has the exact same API as the sort package in the standard library. Therefore, all you have to do is change your import from "sort" to "github.com/dmcmanam/sort" and everything else remains the same.

Example

// This is the same example as the standard library just mentioned here for convenience
package main

import (
    "fmt"
    "github.com/dmcmanam/sort"
)

type Person struct {
    Name string
    Age  int
}

func (p Person) String() string {
    return fmt.Sprintf("%s: %d", p.Name, p.Age)
}

// ByAge implements sort.Interface for []Person based on
// the Age field.
type ByAge []Person

func (a ByAge) Len() int           { return len(a) }
func (a ByAge) Swap(i, j int)      { a[i], a[j] = a[j], a[i] }
func (a ByAge) Less(i, j int) bool { return a[i].Age < a[j].Age }

func main() {
    people := []Person{
        {"Bob", 31},
        {"John", 42},
        {"Michael", 17},
        {"Jenny", 26},
    }

    fmt.Println(people)

    sort.Slice(people, func(i, j int) bool {
        return people[i].Age < people[j].Age
    })
    fmt.Println(people)

}
