golang check if string exists in slice

To check if a string exists in a slice in Go (Golang), you can follow these steps:

1. Declare a slice of strings:

slice := []string{"apple", "banana", "orange"}

1. Iterate through the slice using a for loop:

for _, value := range slice {
    // Check if the current value is equal to the target string
    if value == "orange" {
        // String exists in the slice
        fmt.Println("String exists in the slice.")
        break
    }
}

1. If the current value is equal to the target string, print a message indicating that the string exists in the slice.

2. Use the break statement to exit the loop after finding a match. This is done to optimize the search and avoid unnecessary iterations if the string exists.

Note: This code assumes that you have imported the "fmt" package.
