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 S = sc.next();
        int n = Integer.parseInt(sc.next());

        for (int i = 0; i < n; i++) {
            String op = sc.next();

            int a = Integer.parseInt(sc.next());
            int b = Integer.parseInt(sc.next());

            String bs = S.substring(0, a);
            String ms = S.substring(a, b + 1);
            String as = S.substring(b + 1);

            switch (op) {
                case "replace":
                    S = bs + sc.next() + as;
                    break;
                case "reverse":
                    StringBuilder tmp = new StringBuilder();
                    for (int j = ms.length() - 1; j >= 0; j--) {
                        tmp.append(ms.charAt(j));
                    }

                    S = bs + tmp.toString() + as;
                    break;
                case "print":
                    System.out.println(S.substring(a, b + 1));
                    break;
            }
        }
    }
