Problem:
MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

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 {
	void run() {
		Scanner scan = new Scanner(System.in);
		String str = scan.next();
		int q = scan.nextInt();
		for (int i = 0; i < q; i++) {
			String method = scan.next();
			int a = scan.nextInt();
			int b = scan.nextInt();
			if (method.equals("print")) {
				print(str, a, b);
			} else if (method.equals("reverse")) {
				str = reverse(str, a, b);
			} else if (method.equals("replace")){
				String p = scan.next();
				str = replace(str, a, b, p);
			}
		}
	}
	void print(String str, int a, int b){
		System.out.println(str.substring(a, b + 1));
	}
	String reverse(String str, int a, int b){
		String s = str.substring(a, b + 1);
		StringBuilder strbul = new StringBuilder(s).reverse();
		return str.replace(s, strbul.toString());
	}
	String replace(String str, int a, int b, String p) {
		String s1 = str.substring(0, a);
		String s2 = str.substring(b + 1, str.length());
		return s1 + p + s2;
	}
	public static void main(String[] args) {
		new Main().run();
	}
