Challenge 17 - Decode the Secret
👋 Welcome Gophers! In this challenge, you are tasked with decoding the secret message.
You will need to implement the DecodeSecret function which will take in a string that has been encoded using base64 encoding and decode this string.
This decoded string will be the result of a caesar cipher which has shifted all of the characters of the string up by 1 place. So you will have to ensure that when you return the result, it also decodes this cipher.

package main
import (
"encoding/base64"
"fmt"
)
func DecodeSecret(message string) string {
data, err := base64.StdEncoding.DecodeString(message)
if err != nil {
fmt.Println(err)
}
fmt.Println(string(data))
var secret []rune
for _, char := range data {
fmt.Println(rune(char + 1))
secret = append(secret, rune(char-1))
}
fmt.Println(secret)
return string(secret)
}
func main() {
fmt.Println("Decode the Secret")
message := "VEZEU0ZVVFVTSk9I"
result := DecodeSecret(message)
fmt.Println(result)
}
