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;

public class Main{
	public static void main (String args[]){

		//???????????¨????????°???????????¨???
		Scanner sc = new Scanner(System.in);
		String word = sc.next();
		int q = sc.nextInt();

		//????????°???????????????????????¨???
		for(int i = 0; i < q; i++){
			String command = sc.next();

			//print a b: str str ??? a ??????????????? b ??????????????§??????????????????
			if(command.equals("print")){
				int a = sc.nextInt();
				int b = sc.nextInt();

				String str = word.substring(a,b+1);
				System.out.println(str);
			}

			//reverse a b: str str ??? a ??????????????? b ??????????????§?????????????????????
			if(command.equals("reverse")){
				int a = sc.nextInt();
				int b = sc.nextInt();

				String mae = word.substring(a,b+1);

				StringBuffer sb = new StringBuffer(mae);
				StringBuffer ato = sb.reverse();

				word = word.replace(mae, ato);
			}


			//replace a b p: str str ??? a ??????????????? b ??????????????§??? p ?????????????????????
			if(command.equals("replace")){
				int a = sc.nextInt();
				int b = sc.nextInt();
				String ato = sc.next();

				String mae = word.substring(a,b+1);
				//System.out.println(mae);
				//System.out.println(ato);

				word = word.replace(mae, ato);
				//System.out.println(word);
			}
		}
		sc.close();
	}
