How to Remove Specific Item from a Set in Go - Step by Step Examples

How to Remove Specific Item from a Set in Go ?

Answer

To remove a specific item from a set in Go, you need to manually iterate over the set and create a new set without the item to be removed.


✐ Examples

1 Remove Item '2' from a Set

In this example,

  1. First, we create a set of integers named numberSet with values []int{1, 2, 3, 4, 5}.
  2. Next, we create a new set called updatedSet.
  3. We iterate through each element of numberSet using a for loop.
  4. Within the loop, we check if the current number is equal to '2'. If not, we add it to updatedSet.
  5. After the loop, updatedSet contains all items except '2'.

Go Program

package main

import (
    "fmt"
)

func main() {
    numberSet := []int{1, 2, 3, 4, 5}
    updatedSet := []int{}

    for _, num := range numberSet {
        if num != 2 {
            updatedSet = append(updatedSet, num)
        }
    }

    fmt.Println(updatedSet)
}

Output

[1 3 4 5]

2 Remove String "banana" from a Set

In this example,

  1. First, we create a set of strings named stringSet with values []string{"apple", "banana", "orange"}.
  2. Next, we create a new set called updatedSet.
  3. We iterate through each element of stringSet using a for loop.
  4. Within the loop, we check if the current string is equal to 'banana'. If not, we add it to updatedSet.
  5. After the loop, updatedSet contains all items except 'banana'.

Go Program

package main

import (
    "fmt"
)

func main() {
    stringSet := []string{"apple", "banana", "orange"}
    updatedSet := []string{}

    for _, str := range stringSet {
        if str != "banana" {
            updatedSet = append(updatedSet, str)
        }
    }

    fmt.Println(updatedSet)
}

Output

[apple orange]
