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 JAVA (judge verdict: Accepted)

import java.util.Scanner;
  
class Main{
  public static void main(String args[]){
    Scanner sc = new Scanner(System.in);
    String str = sc.next();
    int n = sc.nextInt();
    for(int i = 0; i < n; i++){
      String stroutput = "";
      String meirei = sc.next();
      if(meirei.equals("print")){
        int a = sc.nextInt();
        int b = sc.nextInt();
        for(int x = a; x <= b; x++){
          char c = str.charAt(x);
          stroutput += c;
        }
      	System.out.println(stroutput);
      }else if(meirei.equals("reverse")){
        int a = sc.nextInt();
        int b = sc.nextInt();
        for(int x = 0; x < a; x++){
          char c = str.charAt(x);
          stroutput += c;
