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.

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 $p$

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.

Examples

Input

abcde
3
replace 1 3 xyz
reverse 0 2
print 1 4


Output

xaze


Input

xyz
3
print 0 2
replace 0 2 abc
print 0 2


Output

xyz
abc
