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 Scala (judge verdict: Accepted)

import scala.io.StdIn.{readLine, readInt}

object Main extends App {
  var str = readLine
  val n = readInt

  for (_ <- 1 to n) {
    val input = readLine.split(" ").map(e => try {
      e.toInt
    } catch {
      case _: Exception => e
    })
    if (input.length == 4) {
      val Array(order: String, pos1: Int, pos2: Int, replaceStr: String) = input
      str = executeOrder(order, pos1, pos2, replaceStr)
    } else {
      val Array(order: String, pos1: Int, pos2: Int) = input
      str = executeOrder(order, pos1, pos2)
    }

    def executeOrder(order: String, pos1: Int, pos2: Int, replaceStr: String = ""): String = {
      val partialString = str.slice(pos1, pos2 + 1)
      order match {
        case s if s == "print" => println(partialString); str
        case s if s == "replace" => str.patch(pos1, replaceStr, pos2 - pos1 + 1).mkString
        case s if s == "reverse" => str.patch(pos1, partialString.reverse, pos2 - pos1 + 1).mkString
      }
    }
  }
