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 line = sc.nextLine();
        char[] str = line.toCharArray();

        line = sc.nextLine();
        int n = Integer.parseInt(line);

        for(int i = 0; i < n; i++) {
          line = sc.nextLine();
          String[] l = line.split(" ");
          String command = l[0];
          int start = Integer.parseInt(l[1]);
          int target = Integer.parseInt(l[2]);

          int len = target - start + 1;
          char[] tmp = new char[len];
          if(command.equals("replace")) {
            char rep[] = l[3].toCharArray();
            for(int j = 0; j < len; j++) {
              str[j + start] = rep[j];
            }
          } else if(command.equals("reverse")) {
            for(int j = 0; j < len; j++) {
              tmp[j] = str[j + start];
            }
            for(int j = 0; j < len; j++) {
              str[target - j] = tmp[j];
            }
          } else if(command.equals("print")) {
            for(int j = 0; j < len; j++) {
              tmp[j] = str[j + start];
            }
            System.out.println(String.valueOf(tmp));
          }

        }

    }
