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;

	public class Class1
	{
		public static void Main()
		{  
			string str=Console.ReadLine();//string
			int numOrders=int.Parse(Console.ReadLine());//number of orders
			
			for(int i=0;i<numOrders;i++)
			{
				string order=Console.ReadLine();
				string[] oab=order.Split();
				int a=int.Parse(oab[1]);//0~
				int b=int.Parse(oab[2]);//0~
				string answer;
				switch (oab[0])
				{
					case "print":
						answer =str.Substring(a,b-a+1);
						Console.WriteLine(answer);
						break;
					case "reverse":
						for(int j=str.Length-1;j>=0;j--)
						{
							Console.Write(str[j]);	
						}
						Console.Write("\r\n");
						break;
					case "replace":
						if(a==0)
						{
							answer=oab[3]+str.Substring(b+1);
						}
											
						answer=str.Substring(0,a)+oab[3]+str.Substring(b+1);
						Console.WriteLine(answer);
						break;
				}
					
			}
		}
