How to check if a slice contains a specific element in Golang?

To check if a slice contains a specific element in Golang, you can use a for loop to iterate through the slice and compare each element with the target element. If a match is found, you can return true. If the loop completes without finding a match, you can return false.

Here's an example:

package main

import "fmt"

func contains(slice []int, target int) bool {
    for _, element := range slice {
        if element == target {
            return true
        }
    }
    return false
}

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

    if contains(slice, target) {
        fmt.Println("Slice contains the target element")
    } else {
        fmt.Println("Slice does not contain the target element")
    }
}

In this example, the contains function takes the slice and the target element as input parameters. It iterates through the slice using a for loop and compares each element with the target element. If a match is found, it returns true. If the loop completes without finding a match, it returns false.

In the main function, we define a slice with some elements and a target element. We then call the contains function and check its return value to determine if the slice contains the target element.
