You are given a string $S$ of length $N$.
What string is formed if we reverse the order of the characters from the $A$-th character to the $B$-th character of $S$, while leaving the other characters unchanged? Here, the first character of $S$ is the $1$-st character, and the last character is the $N$-th character.
Given the string $S$ and $2$ integers $A, B$, write a program to output the string formed by reversing the order of the characters from the $A$-th character to the $B$-th character of $S$.
Input
The input is given from Standard Input in the following format:
$$ \begin{aligned} &N \ A \ B \\ &S \end{aligned} $$
Output
Output on $1$ line the string formed by reversing the order of the characters from the $A$-th character to the $B$-th character of $S$.
Constraints
- $1 \le A \le B \le N \le 200$.
- $S$ is a string of length $N$.
- Each character of $S$ is an uppercase or lowercase English letter.
Examples
Input 1
10 3 7 JOIjoiJoIj
Output 1
JOJiojIoIj
Input 2
9 6 6 abcdefghi
Output 2
abcdefghi
Note 2
- It is possible that $A = B$.
