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

public class Main {
	public static void main(String[] args)throws IOException{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		StringBuffer sb;
		StringBuffer tem;
		String change = null;

		String str = br.readLine();
		int count = Integer.parseInt(br.readLine());
		sb = new StringBuffer(str);

		for(int i = 0; i < count; i++){
			String menu = br.readLine();
			String[] s = menu.split(" ");
			menu = (s[0]);
			int start = Integer.parseInt(s[1]);
			int end = Integer.parseInt(s[2]);

			if(s.length == 4){
				 change = (s[3]);
			}
			if(menu.startsWith("rev")){
				tem = new StringBuffer(sb.substring(start, (end + 1)));
				tem.reverse();
				sb.replace(start, end+1, new String(tem));

			}else if(menu.startsWith("rep")){
				sb.replace(start, end + 1, change);

			}else if(menu.startsWith("p")){
				System.out.println(sb.substring(start, (end + 1)));
			}
		}
	}
