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)

public class Main {
	public static void main(String[] args) {
		try (java.util.Scanner sc = new java.util.Scanner(System.in)) {
			String str = sc.next();
			int cntCommand = sc.nextInt();

			for (int i = 0; i < cntCommand; i++) {
				String command = sc.next();
				int begin = sc.nextInt();
				int end = sc.nextInt();

				if (command.equals("print")) {
					System.out.println(str.substring(begin, end + 1));
				} else if (command.equals("reverse")) {
					str = reverse(begin, end, str);
				} else if (command.equals("replace")) {
					str = replace(begin, end, str, sc.next());
				}
			}

		}
	}

	private static String reverse(int begin ,int end, String str) {
		char[] arr = str.toCharArray();
		int num = end - begin +1;
		
		for (int i = 0; i < (num / 2); i++) {
			char tmp = arr[begin + i];
			arr[begin + i] = arr[end - i];
			arr[end - i] = tmp;
		}
		return String.valueOf(arr);
	}

	private static String replace(int begin, int end, String target, String replacemant) {
		char work[] = target.toCharArray();
		char repl[] = replacemant.toCharArray();

		for (int i = begin; i <= end; i++) {
			work[i] = repl[i - begin];
		}
		return String.valueOf(work);
