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;

class Program {
    private static int Main() {
        var str = Console.ReadLine();

        var input = Console.ReadLine();
        int q = int.Parse( input );

        for( int i =0; i < q; ++i){
            input = Console.ReadLine();
            var values = input.Split( ' ' );

            var a = int.Parse( values[ 1 ] );
            var b = int.Parse( values[ 2 ] );
            switch( values[ 0 ] ) {
                case "replace":
                    str = str.Remove( a, b + 1 - a );
                    str = str.Insert( a, values[ 3 ] );
                    break;
                case "reverse":
                    var tmp = str.Substring( a, b + 1 - a );
                    var reverse = new string( tmp.Reverse().ToArray() );
                    str = str.Remove( a, b + 1 - a );
                    str = str.Insert( a, reverse );
                    break;
                case "print":
                    Console.WriteLine( str.Substring( a, b + 1 - a ) );
                    break;

                default:
                    throw new Exception( "Invalid Data." );

            }
