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.*;

public class Main{
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		char[] str = sc.next().toCharArray();
		int q = sc.nextInt();
		String order;
		int a, b;
		char[] p;
		char tmp;
		for (int i = 0; i < q; i++) {
			order = sc.next();
			a = sc.nextInt();
			b = sc.nextInt();
			switch (order) {
			case "print":
				for (int j = a; j <= b; j++) {
					System.out.print(str[j]);
				}
				System.out.printf("%n");
				break;
			case "reverse":
				for (int j = a, k = b; j <= (b - a) / 2 + a; j++, k--) {
					tmp = str[j];
					str[j] = str[k];
					str[k] = tmp;
				}
				break;
			case "replace":
				p = sc.next().toCharArray();
				for (int j = a, k = 0; j <= b; j++, k++) {
					str[j] = p[k];
				}
				break;
			}
		}
		sc.close();
	}
