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: Wrong Answer)

using System;

class Program
{
    static void Main(string[] args)
    {
        String strData = Console.ReadLine();

        int count = int.Parse(Console.ReadLine());

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

            switch (tmp[0])
            {

                case "replace" :
                    strData = strData.Remove(int.Parse(tmp[1]), int.Parse(tmp[2]));
                    strData = strData.Insert(int.Parse(tmp[1]),tmp[3]);
                    break;

                case "print" :
                    String strPrint = strData.Substring(int.Parse(tmp[1]), int.Parse(tmp[2]));
                    Console.WriteLine(strPrint);
                    break;

                case "reverse" :
                    String s = strData.Substring(int.Parse(tmp[1]), int.Parse(tmp[2]) + 1);
                    char[] chars = s.ToCharArray();
                    Array.Reverse(chars);
                    var ret = new String(chars);
                    strData = strData.Remove(int.Parse(tmp[1]), int.Parse(tmp[2])+1);
                    strData = strData.Insert(int.Parse(tmp[1]), ret);
                    break;

            }

        }
    }
