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 sc = new Scanner(System.in);
        String str=sc.nextLine();
        int q=sc.nextInt();
        String order[][] = new String[q][4];

        for( int i = 0; i < q; i++) {
        	order[i][0]= sc.next();
        	order[i][1]= sc.next();
        	order[i][2]= sc.next();
        	if("replace".equals(order[i][0])) {
            	order[i][3]= sc.next();
        	}
        }
        sc.close();
        for( int i = 0; i < q; i++) {
        	String command = order[i][0];
        	int start = Integer.parseInt(order[i][1]);
        	int end = Integer.parseInt(order[i][2]);
        	if ("replace".equals(command)) {
        		StringBuffer sb = new StringBuffer(str);
        		str = sb.replace(start, end+1, order[i][3]).toString();
        	} else if ("print".equals(command)) {
        		System.out.println(str.substring(start,end +1));
        	} else if ("reverse".equals(command)) {
        		StringBuffer sb = new StringBuffer(str.substring(start,end + 1));
        		String bef = str.substring(start,end+1);
        		String aft = sb.reverse().toString();
        		str = str.replace(bef, aft);
        	}
        }
    }
