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;

class Main {
    public static void main(String args[]) {
        Scanner scan = new Scanner(System.in);
        String str = scan.nextLine();
        int num = Integer.parseInt(scan.nextLine());

        for(int i = 0; i < num; i++) {
            String[] line = scan.nextLine().split(" ");
            String order = line[0];
            int first = Integer.parseInt(line[1]);
            int end = Integer.parseInt(line[2]) + 1;

            if (order.equals("replace")) {
                if (first == 0) {
                    str = line[3].concat(str.substring(end));
                } else if (end == str.length()) {
                    str = str.substring(0, first).concat(line[3]);
                } else {
                    str = str.substring(0, first).concat(line[3]).concat(str.substring(end));
                }

            } else if (order.equals("reverse")) {
                if (first == 0) {
                    str = new StringBuffer(str.substring(0, end)).reverse().toString().concat(str.substring(end));
                } else if(end == str.length()) {
                    str = str.substring(0, first).concat(new StringBuffer(str.substring(first)).reverse().toString());
                } else {
                    str = str.substring(0, first).concat(new StringBuffer(str.substring(first, end)).reverse().toString()).concat(str.substring(end));
                }
            } else if (order.equals("print")) {
                String ans = str.substring(first, end);
                System.out.println(ans);
            }
        }
