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 Scala (judge verdict: Accepted)

import scala.io.Source

object Main {

  def transform(target: String, cmd: Array[String]) = cmd(0) match {
    case "print" => { println(target.slice(cmd(1).toInt, cmd(2).toInt+1)); target }
    case "reverse" => target.take(cmd(1).toInt) + target.slice(cmd(1).toInt, cmd(2).toInt+1).reverse + target.drop(cmd(2).toInt+1)
    case "replace" => target.take(cmd(1).toInt) + cmd(3) + target.drop(cmd(2).toInt+1)
  }

  def main(args: Array[String]): Unit = {
    val src = Source.stdin.getLines
    val target = src.next
    src.next
    src.map(_.split(" ")).foldLeft(target)(transform)
  }
