How to Convert a Set of Integers to a Set of Strings in Go

How to Convert a Set of Integers to a Set of Strings in Go ?

Answer

In Go, you can convert a set of integers to a set of strings by iterating over each element of the integer set and converting it to a string using the strconv.Itoa() function.


✐ Examples

1 Convert a Set of Integers to a Set of Strings using strconv.Itoa() Function

In this example,

  1. We have a set of integers named intSet1 containing the elements 1, 2, 3, 4, 5.
  2. We create an empty set named stringSet1.
  3. We iterate over each element of intSet1 using a for range loop.
  4. Inside the loop, we convert each integer element to a string using the strconv.Itoa() function and add it to the stringSet1.
  5. We print the resulting stringSet1 to standard output.

Go Program

package main

import (
	"fmt"
	"strconv"
)

func main() {
	intSet1 := map[int]struct{}{1: {}, 2: {}, 3: {}, 4: {}, 5: {}}
	stringSet1 := map[string]struct{}{}
	for num := range intSet1 {
		str := strconv.Itoa(num)
		stringSet1[str] = struct{}{}
	}
	fmt.Println(stringSet1)
}

Output

map[1:{} 2:{} 3:{} 4:{} 5:{}]

2 Convert a Set of Integers to a Set of Strings using strconv.Itoa() Function with Different Integers

In this example,

  1. We have a set of integers named intSet2 containing the elements 10, 20, 30, 40, 50.
  2. We create an empty set named stringSet2.
  3. We iterate over each element of intSet2 using a for range loop.
  4. Inside the loop, we convert each integer element to a string using the strconv.Itoa() function and add it to the stringSet2.
  5. We print the resulting stringSet2 to standard output.

Go Program

package main

import (
	"fmt"
	"strconv"
)

func main() {
	intSet2 := map[int]struct{}{10: {}, 20: {}, 30: {}, 40: {}, 50: {}}
	stringSet2 := map[string]struct{}{}
	for num := range intSet2 {
		str := strconv.Itoa(num)
		stringSet2[str] = struct{}{}
	}
	fmt.Println(stringSet2)
}

Output

map[10:{} 20:{} 30:{} 40:{} 50:{}]
