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: Wrong Answer)

import java.util.Scanner;
class Main {
	static String reverse(String target){
		String ret="";
		for(int i=target.length()-1;0<=i;i--){
			ret+=target.charAt(i);
		}
		return ret;
	}
	public static void main(String[] args) {
		Scanner scan=new Scanner(System.in);
		String str=scan.next();
		int q=scan.nextInt();
		String cmd;
		int a,b;
		for(int i=0;i<q;i++){
			cmd=scan.next();
			if(cmd.equals("replace")){
				a=scan.nextInt();
				b=scan.nextInt();
				cmd=scan.next();
				str=str.replace(str.substring(a,b+1),cmd);
			}else if(cmd.equals("reverse")){
				a=scan.nextInt();
				b=scan.nextInt();
				String r=reverse(str.substring(a,b+1));
				cmd=str.substring(0,a);
				cmd+=r;
				cmd+=str.substring(b+1,str.length());
				str=cmd;
			}else{
				a=scan.nextInt();
				b=scan.nextInt();
				System.out.println(str.substring(a,b+1));
			}
		}
		scan.close();
	}
