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.io.*;

class Main {
	public static void main(String[] args) {
		BufferedReader kb = new BufferedReader( new InputStreamReader( System.in ) );
		try {
			String str = kb.readLine();
			int q = Integer.parseInt( kb.readLine() );
			
			StringBuilder output = new StringBuilder( 1000+1 );
			int start, end;
			while( 0 < q-- ) {
				String[] instruction = kb.readLine().split( " " );
				start = Integer.parseInt( instruction[1] );
				end = Integer.parseInt( instruction[2] );
				if( instruction[0].equals( "print" ) ) {
		        	System.out.println( str.substring( start, end+1 ) );
				} else if( instruction[0].equals( "reverse" ) ) {
					output.append( str.substring( start, end+1 ) );
					output.reverse();
					output.insert( 0, str.substring( 0, start )  );
					output.append( str.substring( end+1 ) );
					str = output.toString();
				} else if( instruction[0].equals( "replace" ) ) {
					output.append( str );
					output.replace( start, end+1, instruction[3]  );
					str = output.toString();
				}
				output.setLength( 0 );
			}
				        
		} catch( IOException e ) {
			System.err.println( e );
		}
	}
