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 {
	
	private static StringBuilder answer = new StringBuilder();
	
	private static String PRINT   = "print";

		for(int i = 0; i<numbers;i++){
			
			String command = sc.next();
						
			target = operate(command,target,sc);
			
		}
		
		System.out.print(answer);
		
		sc.close();
	}

	private static String operate(String command, String target,Scanner sc) {
		
		if(PRINT.equalsIgnoreCase(command)){
			
			int a  = Integer.parseInt(sc.next());
