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;
class change{
  public String replace(String str, int first, int last, String comp){
    String strf = str.Substring(0,first);
    String strl = str.Substring(last+1,str.Length-last-1);
    String newstring = strf+comp+strl;
    return newstring;
  }
  public String reverse(String str, int first, int last){
    String temp,rev=null;
    temp = str.Substring(first,last-first+1);
    for(int i=last; i>=first; i--){
      rev+=str[i];
    }
    str = str.Replace(temp,rev);
    return str;
  }
  public void print(String str, int first, int last){
    for(int i=first; i<=last; i++){
      Console.Write(str[i]);
    }
    Console.WriteLine();
  }
}

class code{
  public static void Main(){
    change c = new change();
    String str = Console.ReadLine();
    String[] command;
    int numofcom = int.Parse(Console.ReadLine());
    for(int i=0; i<numofcom; i++){
      command = Console.ReadLine().Split(' ');
      switch (command[0]){
        case "replace":
          str = c.replace(str, int.Parse(command[1]), int.Parse(command[2]), command[3]);
          break;
        case "reverse":
          str = c.reverse(str, int.Parse(command[1]), int.Parse(command[2]));
          break;
        case "print":
          c.print(str, int.Parse(command[1]), int.Parse(command[2]));
          break;
        default:
          break;
      }
    }
  }
