Sorting

Context

The sort package provides sorting for built‑in types and custom sorts via sort.Interface. For slices of ints, floats, or strings, use sort.Ints, sort.Float64s, sort.Strings.

Example

Sort slices of ints and strings.

Code example

package main

import (
    "fmt"
    "sort"
)

func main() {
    ints := []int{5, 2, 8, 1, 9}
    sort.Ints(ints)
    fmt.Println(ints)

    strs := []string{"banana", "apple", "cherry"}
    sort.Strings(strs)
    fmt.Println(strs)

    // Check if sorted
    fmt.Println(sort.IntsAreSorted(ints))
}

Output

[1 2 5 8 9]
[apple banana cherry]
true
