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 Ruby (judge verdict: Accepted)

#!/usr/bin/env ruby

if __FILE__ == $0 then
	s = gets.chomp
	q = gets.chomp.to_i

	q.times do
		op = gets.split
		a, b = op[1,2].map(&:to_i)
		p  = op[3]

		case op[0]
		when 'print' then
			puts s[a..b]
		when 'reverse'
            s = s[0,a] + s[a..b].reverse + s[b+1..-1]
		when 'replace'
            s = s[0,a] + p + s[b+1..-1]
		end
	end
end
