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 Python (judge verdict: Wrong Answer)

# -*- coding: utf-8 -*-

s = str(raw_input())
q = int(raw_input())
for i in range(q):
    line = map(str, raw_input().split())
    com = line[0]
    a = int(line[1])
    b = int(line[2])
    if com == "print":
        print s[a:b+1]
    elif com == "reverse":
        tmp = s[::-1]
        s = s[0:a] + tmp[len(tmp)-b-1:len(tmp)-a] + s[b+1:]
    elif com == "replace":
        p = line[3]
        s = s.replace(s[a:b+1], p)
    else:
        print "Error"
