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 PHP (judge verdict: Accepted)

<?php
// Your code here!
    $string = trim(fgets(STDIN));
    $num = intval(trim(fgets(STDIN)));
    while($line = trim(fgets(STDIN))){
        $line = explode(" ",$line);
        if($line[0]== "print"){
            $string_a = substr($string,$line[1],$line[2]-$line[1]+1);
            echo $string_a."\n";
        }elseif($line[0]== "replace"){
            $string = substr_replace($string,$line[3],$line[1],$line[2]-$line[1]+1);
        }elseif($line[0]== "reverse"){
            $line_a = substr($string,$line[1],$line[2]-$line[1]+1);
            $line_a = strrev($line_a);
            $string = substr_replace($string,$line_a,$line[1],$line[2]-$line[1]+1);
        }
    }
?>
