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) {
		// TODO 自動生成されたメソッド・スタブ
		Scanner scanner = new Scanner(System.in);
		// 文字列入力strLine
		String strLine = scanner.next();
		// 命令回数intCommand
		int intCount = scanner.nextInt();

		for (int intI = 0; intI < intCount; intI++) {
			// 命令strCommand入力
			String strCommand = scanner.next();
			// 各条件で処理
			if (("print").equals(strCommand)) {
				int intBegin = scanner.nextInt();
				int intEnd = scanner.nextInt();
				System.out.println(strLine.substring(intBegin, intEnd + 1));

			} else if (("reverse").equals(strCommand)) {
				int intBegin = scanner.nextInt();
				int intEnd = scanner.nextInt();
				// 指定部分を切り抜き反転し置換
				StringBuilder strReverse = new StringBuilder(strLine.substring(intBegin, intEnd + 1));
				strReverse.reverse();
				StringBuilder strReLine = new StringBuilder(strLine);
				strReLine.replace(intBegin, intEnd + 1, strReverse.toString());
				// strLineを上書き
				strLine = strReLine.toString();

			} else if (("replace").equals(strCommand)) {
				int intBegin = scanner.nextInt();
				int intEnd = scanner.nextInt();
				// 置換する文字列strReplace読み込み
				String strReplace = scanner.next();
				StringBuilder strReLine = new StringBuilder(strLine);
				// intBegin～intEnd文字目をstrReplaceに置換
				strReLine.replace(intBegin, intEnd + 1, strReplace);
				// strLineにstrReLineで上書き
				strLine = strReLine.toString();
			}
		}
