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)

def print(s, a, b)
  puts s[a..b]
end

def reverse(s, a, b)
  chunk = s[a..b]
  s[a..b] = chunk.reverse
  s
end

def replace(s, a, b, p)
  s[a..b] = p
  s
end

s = gets.chomp
q = gets.chomp.to_i

q.times do
  c = gets.chomp.split
  c[1] = c[1].to_i
  c[2] = c[2].to_i
  case c[0]
  when "print" then print(s, c[1], c[2])
  when "reverse" then s = reverse(s, c[1], c[2])
  when "replace" then s = replace(s, c[1], c[2], c[3])
  end
end
