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 C# (judge verdict: Accepted)

using System;
using System.Linq;

public class Program
{
    public static void Main()
    {
        string strData = Console.ReadLine();
        int count = int.Parse(Console.ReadLine());

        for (int i = 0; i < count; i++)
        {
            string[] tmp = Console.ReadLine().Split(' ');

            int startNum = int.Parse(tmp[1]);
            int endNum = int.Parse(tmp[2]);
            int len = endNum - startNum + 1;

            if ("print" == tmp[0])
            {
                Console.WriteLine(strData.Substring(startNum, len));
            }
            else if ("reverse" == tmp[0])
            {
                string t = new string(strData.Substring(startNum, len).Reverse().ToArray());
                strData = strData.Substring(0, startNum) + t + strData.Substring(endNum + 1);
            }
            else if ("replace" == tmp[0])
            {
                strData = strData.Substring(0, startNum) + tmp[3] + strData.Substring(endNum + 1);
            }
        }
    }
