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: Wrong Answer)

<?php
  $str = trim(fgets(STDIN));
  $num = trim(fgets(STDIN));
  for($i = 0; $i < $num; $i++) {
    // list($a, $b, $c, $d) = explode(" ", trim(fgets(STDIN)));
    $d = explode(" ", trim(fgets(STDIN)));
    if ($d[0] == "print") {
      if ($i == ($num-1)) {
        print(substr($str, $d[1], ($d[2]+1)));
      } else {
        print(substr($str, $d[1], ($d[2]+1)) . "\n");
      }
    } else if ($d[0] == "reverse") {
      $x = substr($str, $d[1], ($d[2]+1));
      $x = strrev($x);
      $str = substr_replace($str, $x, $d[1], ($d[2]+1));
    } else if ($d[0] == "replace") {
      $str = substr_replace($str, $d[3], $d[1], $d[2]);
    }
  }
?>
