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: Wrong Answer)

import scala.io.Source

object Main {

  def transform(src: Iterator[String], target: String, n: Int): String = {
    if (n <= 0) target
    else {
      val Array(action, start, end, sub @ _*) = src.next.split(" ")
      if (action == "replace") transform(src, target.patch(start.toInt, sub.head, end.toInt - start.toInt + 1), n-1)
      else if (action == "reverse") transform(src, reversePartially(start.toInt, end.toInt, target), n-1)
      else transform(src, printPartially(start.toInt, end.toInt, target), n-1)
    }
  }

  def reversePartially(start: Int, end: Int, str: String): String = {
    val reversedPart = str.take(end+1).drop(start).reverse
    str.patch(start, reversedPart, end - start +1 )
  }

  def printPartially(start: Int, end: Int, str: String): String = {
    val printPart = str.take(end+1).drop(start)
    println(printPart)
    printPart
  }

  def main(args: Array[String]): Unit = {

    val src = Source.stdin.getLines
    val target = src.next
    val numOfLines = src.next.toInt

    transform(src, target, numOfLines)
  }

}
