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

/**
  * AOJ
  */
object Main {

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

    var str = StdIn.readLine()
    val q =  StdIn.readInt()

    for(_ <- 1 to q){

      val line = StdIn.readLine().split(" ")
      val a = line(1).toInt
      val b = line(2).toInt

      line(0) match {
        case "replace" => {
          str = str.take(a) + line(3) + str.takeRight(str.length - b - 1)
        }
        case "reverse" => {
          str = str.take(a) + str.slice(a,b + 1).reverse + str.takeRight(str.length - b - 1)
        }
        case "print"   => println(str.slice(a,b + 1))
      }
    }
  }
}
