    public static String caesarCipher(String s, int k) {
    // Write your code here
    StringBuilder answer = new StringBuilder();
    for(char ch : s.toCharArray()) {
        if(Character.isLetter(ch)) {
            char base = Character.isUpperCase(ch) ? 'A' : 'a';
            answer.append((char)((ch-base+k)%26+base));
        } else {
            answer.append(ch);
        }
        
    }
    return answer.toString();
