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.*;

public class Main{
    public static void main(String[] args){
        Scanner stdIn = new Scanner(System.in);
		String s = stdIn.next();
		int q = stdIn.nextInt();

		for (int i=0; i<q; i++) {
			String com = stdIn.next();
			int a = stdIn.nextInt();
			int b = stdIn.nextInt();

			if(com.equals("reverse")){
				String rev = s.substring(a,b+1);
				String temp = s.substring(b+1);
				s = s.substring(0,a);
				for (int index=rev.length()-1; index>=0; index--) {
					s += rev.charAt(index);
				}
				s += temp;

			}else if(com.equals("replace")){
				String p = stdIn.next();
				s = s.substring(0,a) + p + s.substring(b+1);

			}else{
				String temp = s.substring(a,b+1);
				System.out.println(temp);
			}
		}
    }
}
