How to reverse the characters in a string in Golang?

To reverse the characters in a string in Golang, you can use the following steps:

Convert the string into a slice of runes.
Iterate through the slice and swap the characters at opposite positions.
Convert the slice of runes back into a string.

Here's an example implementation:

package main

import (
    "fmt"
)

func reverseString(s string) string {
    // Convert string to a slice of runes
    runes := []rune(s)

    // Iterate through the slice and swap characters at opposite positions
    for i, j := 0, len(runes)-1; i < j; i, j = i+1, j-1 {
        runes[i], runes[j] = runes[j], runes[i]
    }

    // Convert slice of runes back to string
    return string(runes)
}

func main() {
    s := "Hello, World!"
    reversed := reverseString(s)
    fmt.Println(reversed) // Outputs: "!dlroW ,olleH"
}

In this example, we define a reverseString function that takes a string as input and returns the reversed string. We convert the string to a slice of runes, iterate through the slice to swap the characters, and then convert the slice back to a string. Finally, we call the reverseString function in the main function to demonstrate the reversal.
