How to Sort Items of a Set in Go ?

Answer

To sort items of a Set in Go, you can convert the Set to a slice and use the sort package.


✐ Examples

1 Sort Items of a Set of Numbers

In this example,

  1. We create a Set named numberSet using a map where the keys represent the numbers.
  2. We extract the numbers from the Set and store them in a slice numbers.
  3. We then sort the slice numbers using the sort.Ints() function from the sort package.
  4. Finally, we print the sorted slice to the console.

Go Program

package main

import (
	"fmt"
	"sort"
)

func main() {
	numberSet := map[int]struct{}{5: {}, 3: {}, 8: {}, 1: {}, 2: {}}
	numbers := make([]int, 0, len(numberSet))
	for num := range numberSet {
		numbers = append(numbers, num)
	}
	sort.Ints(numbers)
	fmt.Println("Sorted slice:", numbers)
}

Output

Sorted slice: [1 2 3 5 8]

2 Sort Items of a Set of Strings

In this example,

  1. We create a Set named stringSet using a map where the keys represent the strings.
  2. We extract the strings from the Set and store them in a slice strings.
  3. We then sort the slice strings using the sort.Strings() function from the sort package.
  4. Finally, we print the sorted slice to the console.

Go Program

package main

import (
	"fmt"
	"sort"
)

func main() {
	stringSet := map[string]struct{}{"banana": {}, "apple": {}, "cherry": {}, "date": {}}
	strings := make([]string, 0, len(stringSet))
	for str := range stringSet {
		strings = append(strings, str)
	}
	sort.Strings(strings)
	fmt.Println("Sorted slice:", strings)
}

Output

Sorted slice: [apple banana cherry date]
