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) {
		// TODO ?????????????????????????????????????????????
		java.util.Scanner scan = new java.util.Scanner(System.in);
		java.lang.StringBuilder sb = new java.lang.StringBuilder();

		java.lang.String str = scan.nextLine();
		int q = scan.nextInt();
		scan.nextLine();
		//System.out.println(str);

		for (int i = 0; i < q; i++) {
			String meirei = scan.next();

			if ( "print".equals( meirei ) ) {
				int a = scan.nextInt();
				int b = scan.nextInt();
				System.out.println( str.substring(a, b+1) );
				scan.nextLine();
			} else if ( "reverse".equals( meirei ) ) {
				int a = scan.nextInt();
				int b = scan.nextInt();
				String substr = str.substring(a, b+1);
				java.lang.StringBuilder subsb = new StringBuilder();
				subsb.append(substr).reverse();
				str = str.substring(0, a) + subsb.toString() + str.substring(b+1);
				scan.nextLine();
				//System.out.println(str);
			} else if ( "replace".equals( meirei ) ) {
				int a = scan.nextInt();
				int b = scan.nextInt();
				String p = scan.next();
				str = str.substring(0, a) + p + str.substring(b+1);
				//System.out.println(str);
			}
		}
	}
