Problem:
MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

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: Wrong Answer)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;



public class Main{
	public static void main(String[] args){

		BufferedReader reader=new BufferedReader(new InputStreamReader(System.in));
		int num, a, b;
		String str, command, p;
		String[] array_command;
		char[] array_str, p_str;
		char x;


		try{
			str=reader.readLine();
			num=Integer.parseInt(reader.readLine());

			for(int i=0;i<num;i++){
				command=reader.readLine();
				array_command=command.split(" ");
				a=Integer.parseInt(array_command[1]);
				b=Integer.parseInt(array_command[2]);


				if(command.matches(".*print.*")){
					System.out.println(str.substring(a, b+1));

				}else if(command.matches(".*reverse.*")){
					array_str=str.toCharArray();
					for(int j=a;j<((a+b)/2);j++){
						x=array_str[j];
						array_str[j]=array_str[b+j-a];
						array_str[b+j-a]=x;
					}
					str=String.valueOf(array_str);

				}else if(command.matches(".*replace.*")){
					p=array_command[3];
					p_str=p.toCharArray();
					array_str=str.toCharArray();

					for(int j=a;j<b+1;j++){
						array_str[j]=p_str[j-a];
					}
					str=String.valueOf(array_str);
				}
