class Solution {
    public String solution(String my_string, int s, int e) {
        StringBuilder answer = new StringBuilder();
        
        answer.append(my_string.substring(0, s));
        answer.append(new StringBuilder(my_string.substring(s, e+ 1)).reverse());      
        answer.append(my_string.substring(e + 1));
        
        return answer.toString();
    }
}

 

코드(Python)

def solution(my_string, s, e):
    return my_string[:s] + my_string[s:e+1][::-1] + my_string[e+1:]
