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 sc = new Scanner(System.in);
        String str = sc.next();
        int q = sc.nextInt();
        for(int i = 0; i < q; i++){
            String order = sc.next();
            int a = sc.nextInt();
            int b = sc.nextInt();
            if(order.equals("print")){
                if(b == str.length() - 1){
                    System.out.println(str.substring(a));
                }else{
                    System.out.println(str.substring(a, b + 1));
                }
            }else if(order.equals("reverse")){
                if(b == str.length() - 1){
                    StringBuffer sb = new StringBuffer(str.substring(a));
                    sb = sb.reverse();
                    str = str.substring(0, a) + sb.toString();
                }else{

                    sb = sb.reverse();
                    str = str.substring(0, a) + sb.toString() + str.substring(b + 1);
                }
            }else if(order.equals("replace")){
                String p = sc.next();
                if(b == str.length() - 1){

                }else{
                    str = str.substring(0, a) + p + str.substring(b + 1);
