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 PHP (judge verdict: Accepted)

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

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

  if ($order == "print")
    echo substr($str, $a, $len) . "\n";
  elseif ($order == "reverse")
    $str = substr_replace(
      $str,
      strrev(substr($str, $a, $len)),
      $a,
      $len
    );
  else
    $str = substr_replace($str, $line[3], $a, $len);
}
