output_description: For each print command, print a string in a line.
input_description: 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.

problem_description: 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.
