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: Accepted)

import java.util.Scanner;

public class Main{
	public static void main(String [] args){
		Scanner sc = new Scanner(System.in);
		String str = sc.next();
		String command;
		int query = sc.nextInt();
		int a,b;
		for(int i = 0; i < query; i++){
			command = sc.next();
			a = sc.nextInt();
			b = sc.nextInt();
			if(command.compareTo("print") == 0){
				System.out.println(str.substring(a,b+1));
			}else if(command.compareTo("reverse") == 0){
				StringBuffer sb = new StringBuffer(str.substring(a,b+1));
				str = str.substring(0,a) + sb.reverse().toString() + str.substring(b+ 1,str.length());
			}else if(command.compareTo("replace") == 0){
				String work = sc.next();
				str = str.substring(0,a) + work + str.substring(b + 1,str.length());
			}
		}
	}
