How to check if a Specific Item is present in the Set in Go ?

Answer

To check if a specific item is present in a Set in Go, you can use a map with a boolean value indicating presence.

✐ Examples

1 Check if Item is Present

In this example,

We define a map named mySet with keys as the elements of the set and boolean values indicating presence.
We set the value of the map to true for items present in the set.
We use the map to check if a specific item is present by accessing the value associated with the key.
The value associated with the key will be true if the item is present in the set, otherwise it will be false.
Finally, we print the result to standard output.

Go Program

package main

import "fmt"

func main() {
    // Define map representing the Set
    mySet := map[string]bool{"apple": true, "banana": true, "orange": true, "grape": true, "melon": true}

    // Check if item is present
    item := "banana"
    isPresent := mySet[item]

    // Print result
    fmt.Printf("Is %s present in the Set? %t\n", item, isPresent)
}

Output

Is banana present in the Set? true

2 Check if Item is Not Present

In this example,

We define a map named mySet with keys as the elements of the set and boolean values indicating presence.
We set the value of the map to true for items present in the set.
We use the map to check if a specific item is not present by accessing the value associated with the key.
The value associated with the key will be false if the item is not present in the set.
Finally, we print the result to standard output.

Go Program

package main

import "fmt"

func main() {
    // Define map representing the Set
    mySet := map[string]bool{"apple": true, "banana": true, "orange": true, "grape": true, "melon": true}

    // Check if item is not present
    item := "peach"
    isNotPresent := !mySet[item]

    // Print result
    fmt.Printf("Is %s not present in the Set? %t\n", item, isNotPresent)
}

Output

Is peach not present in the Set? true
