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 PHP (judge verdict: Accepted)

<?php
    $str = trim(fgets(STDIN));
    $record_cound = trim(fgets(STDIN));

    for($i = 0; $i < $record_cound; $i++){
        $order = explode(" ",trim(fgets(STDIN)));
        $a = $order[1];
        $b = $order[2];
        $length = $b - $a + 1;

        switch ($order[0]){
            case 'print':
                print substr($str, $a, $length)."\n";
                break;
            case 'reverse':
                $str = substr_replace($str, strrev(substr($str, $a, $length)), $a, $length);
                break;
            case 'replace':
                $str = substr_replace($str, $order[3], $a, $length);
                break;
        }
    }
