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 {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		String str = sc.nextLine();
		StringBuilder sb = new StringBuilder(str);

		String string = sc.nextLine();
		int q = Integer.parseInt(string);



		for (int i = 0; i < q; i++) {
			String line = sc.nextLine();
			String[] order = line.split(" ");
			int a = Integer.parseInt(order[1]);
			int b = Integer.parseInt(order[2])+1;

			if (order[0].equals("print")) {
				System.out.println(sb.substring(a, b));
			} else if (order[0].equals("reverse")) {
				StringBuilder SB = new StringBuilder(sb.substring(a, b));
				sb.replace(a, b, SB.reverse().toString());
			} else if (order[0].equals("replace")) {
				sb.replace(a, b, order[3]);
			}
		}

	}
