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.*;

public class Main{
    public static void main(String[] args){
        Scanner scan=new Scanner(System.in);
        String words=scan.next(),operationCode,repwords;
        int result,code1,code2;
        int n=scan.nextInt();
        
        for(int i=0; i<n; i++){
            operationCode=scan.next();
            code1=scan.nextInt();
            code2=scan.nextInt();
            StringBuffer strline;
            
            switch(operationCode){
                case "print":
                    System.out.println(words.substring(code1,code2+1));
                    break;
                case "reverse":

                    words=words.substring(0, code1)+strline.reverse().toString()+words.substring(code2+1);
                    break;
