How to Access Items in a Set in Go ?

Answer

To access items in a set in Go, you can use a map data structure.

✐ Examples

1 Access Items in a Set

In this example,

We create a map named set with initial values representing a set.
We iterate over the map using a for loop to access each item in the set.
We check if a specific item exists in the set by accessing the map with the item's key.
Finally, we print the items in the set and check if a specific item is present.

Go Program

package main

import (
	"fmt"
)

func main() {
	// Create a set using a map with initial values
	set := map[string]bool{
		"apple":  true,
		"banana": true,
		"cherry": true,
	}

	// Access items in the set
	fmt.Println("Items in the set:")
	for item := range set {
		fmt.Println(item)
	}

	// Check if an item exists in the set
	target := "banana"
	if set[target] {
		fmt.Println(target, "is in the set")
	} else {
		fmt.Println(target, "is not in the set")
	}
}

Output

Items in the set:
apple
banana
cherry
banana is in the set
