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.util.*;

public class Main {
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		String str = sc.next();
		int q=sc.nextInt();
		for(int i=0;i<q;i++){
			String or= sc.next();
			if(or.equals("print")){
				int a=sc.nextInt();
				int b=sc.nextInt();
				for(int j=a;j<=b;j++){
					System.out.print(str.charAt(j));
				}
				System.out.println();
			}else if(or.equals("reverse")){
				int a=sc.nextInt();
				int b=sc.nextInt();
				String rev = str.substring(a,b+1);
				StringBuffer revsb=new StringBuffer(rev);
				StringBuffer strsb=new StringBuffer(str);
				revsb=revsb.reverse();
				rev=revsb.toString();
				strsb=strsb.replace(a, b+1, rev);
				str=strsb.toString();
			}else{
				int a=sc.nextInt();
				int b=sc.nextInt();
				String r=sc.next();
				StringBuffer repsb=new StringBuffer(str);
				repsb=repsb.replace(a, b+1, r);
				str=repsb.toString();
			}
		}
	}
