Problem

You are given a string S of length N.

If you reverse the order of the characters from the A-th character to the B-th character of S and leave the other characters unchanged, what string do you get? The first character of S is the 1st character, and the last character is the N-th character.

Given a string S and two integers A, B, write a program that prints the string obtained 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.

N A B
S

Output

Print on one line the string obtained by reversing the order of the characters from the A-th character to the B-th character of S.

Constraints

1 ≦ A ≦ B ≦ N ≦ 200.
S is a string of length N.
Each character of S is an uppercase or lowercase English letter.
