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.Scanner;

public class Main{
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        StringBuilder str = new StringBuilder(scan.next());	//文字列入力
        int count = scan.nextInt();	//命令回数入力

        for(int i=0; i<count; i++) {

        	String com = scan.next();

    		int a = scan.nextInt();	//入力
    		int b = scan.nextInt() + 1;	//入力

        	switch(com) {

        	case "print":

        		System.out.println(str.substring(a, b));
        		break;

        	case "replace":

        		String p = scan.next();
        		str.replace(a,b, p);
        		break;

        	case "reverse":

        		String c = str.substring(a, b);
        		StringBuilder str2 = new StringBuilder(c);
        		str2.reverse();
        		str.replace(a,b,str2.toString());
        		break;

        	}

        }
    }
