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.*;

class Main{
	public static void main(String[] args){
		StringBuffer sb = new StringBuffer();
		Scanner sc =new Scanner(System.in);
		String str = sc.nextLine();
		int q = Integer.parseInt(sc.nextLine());
		for(int i=0;i<q;i++){
			String[] line=sc.nextLine().split(" ");
			int a=Integer.parseInt(line[1]);
			int b=Integer.parseInt(line[2]);
		//index	
			int index=0;
			if(line[0].equals("print")){
				index=1;
			}else if(line[0].equals("reverse")){
				index=2;
			}else if(line[0].equals("replace")){
				index=3;
			}
			switch(index){
				case 1:
					System.out.println(str.substring(a,b+1));
					break;
				case 2:
					String[] strReverse = new String[b-a+1];
					for(int j=b;j>a-1;j--){
						sb.append(str.charAt(j));
					}
					String str1=str.substring(0,a);
					String str2=str.substring(b+1);
					str = str1+sb.toString()+str2;
					break;	
				case 3:
					String str3=str.substring(0,a);
					String str4=str.substring(b+1);
					str = str3+line[3]+str4;
					break;
			}
		//	System.out.println(i+": "+str);
		}
	}
