Transformation

Write a program which performs a sequence of commands to a given string $str$. The command is one of:

print a b: print from the a-th character to the b-th character of $str$

reverse a b: reverse from the a-th character to the b-th character of $str$

replace a b p: replace from the a-th character to the b-th character of $str$ with p

Note that the indices of $str$ start with 0.

Input

In the first line, a string $str$ is given. $str$ consists of lowercase letters. In the second line, the number of commands q is given. In the next q lines, each command is given in the above mentioned format.

Output

For each print command, print a string in a line.

Constraints

$1 \leq $ length of $str \leq 1000$

$1 \leq q \leq 100$

$0 \leq a \leq b < $ length of $str$

for replace command, $b - a + 1 = $ length of $p$

Sample Input 1

abcde
3
replace 1 3 xyz
reverse 0 2
print 1 4

Sample Output 1

xaze

Sample Input 2

xyz
3
print 0 2
replace 0 2 abc
print 0 2

Sample Output 2

xyz
abc

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {
    public static void main(String[] args){
        Scanner scanner = new Scanner(System.in);

        StringBuilder str = new StringBuilder(scanner.nextLine());
        int q = Integer.parseInt(scanner.nextLine());

        for(int i = 0; i < q; i++){
            String command = scanner.next();
            if(command.equals("replace")){
                int start = Integer.parseInt(scanner.next());
                int end = Integer.parseInt(scanner.next()) + 1;
                String text = scanner.next();
                str.replace(start, end, text);
            }else if(command.equals("reverse")){
                int start = Integer.parseInt(scanner.next());
                int end = Integer.parseInt(scanner.next()) + 1;
                StringBuilder sub = new StringBuilder(str.substring(start, end));
                sub.reverse();
                str.replace(start, end, sub.toString());

            }else if(command.equals("print")){
                int start = Integer.parseInt(scanner.next());
                int end = Integer.parseInt(scanner.next()) + 1;
                System.out.println(str.substring(start, end));
            }
        }

        scanner.close();
    }
}
