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[]) throws IOException{
		BufferedReader buf = new BufferedReader(new InputStreamReader(System.in));
		String str = buf.readLine();
		String[] s;
		int q = Integer.parseInt(buf.readLine());
		StringBuilder sb = new StringBuilder();

		for(int i=0; i<q; i++){
			s = buf.readLine().split(" ");
			int a = Integer.parseInt(s[1]);
			int b = Integer.parseInt(s[2]);
			if(s[0].equals("replace")){
				sb.append(str);
				sb.replace(a,b+1,s[3]);
				str = sb.toString();
			}
				sb.setLength(0);
			if(s[0].equals("reverse")){
				sb.append(str.substring(a,b+1));
				String x = sb.reverse().toString();
				sb.setLength(0);
				sb.append(str);			
				sb.replace(a,b+1,x);
				str = sb.toString();
				sb.setLength(0);

			}
			if(s[0].equals("print")){
				System.out.println(str.substring(a,b+1));
			}
		}	
		//System.out.println(str);
			
	}
}
