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

        try (Scanner sc = new Scanner(System.in)) {
            StringBuilder S = new StringBuilder(sc.next());
            int N = sc.nextInt();
            for (int i = 0; i < N; i++) {
                String operator = sc.next();
                int a = sc.nextInt(), b = sc.nextInt() + 1;
                if (operator.equals("print")) {
                    System.out.println(S.substring(a, b));
                } else if (operator.equals("reverse")) {
                    S.replace(a, b, (new StringBuilder(S.substring(a, b))).reverse().toString());
                } else {
                    String x = sc.next();
                    S.replace(a, b, x);
                }
            }
        }
