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;
public class Hello{
    
    public static void replace(string x,string y,string rep)
    {
        //forの中で0から文字数まで回してa~bの間ならみたいなコードにする
        int a=int.Parse(x);
        int b=int.Parse(y);
        string str="";

            {
                str+=rep[aida];
                aida++;
            }
            else str+=target[i];
        }
        target=str;

            if(str[0]=="replace")replace(str[1],str[2],str[3]);
            else if(str[0]=="reverse")reverse(str[1],str[2]);
            else print(str[1],str[2]);
