问题陈述

给定正整数 $N$，$L$ 和 $R$。 对于长度为 $N$ 的序列 $A = (1, 2, \dots, N)$，执行了一次反转第 $L$ 个到第 $R$ 个元素的操作。 打印出执行此操作后的序列。

Problem Statement

You are given positive integers $N$, $L$, and $R$.
For a sequence $A = (1, 2, \dots, N)$ of length $N$, an operation of reversing the $L$-th through $R$-th elements was performed once.
Print the sequence after this operation.

Constraints

• All input values are integers.
• $1 \leq L \leq R \leq N \leq 100$

Input

The input is given from Standard Input in the following format:

$N$ $L$ $R$

Output

Let $A' = (A'_1, A'_2, \dots, A'_N)$ be the sequence after the operation. Print it in the following format:

$A'_1$ $A'_2$ $\dots$ $A'_N$

Sample Input 1

5 2 3

Sample Output 1

1 3 2 4 5

Initially, $A = (1, 2, 3, 4, 5)$.
After reversing the second through third elements, the sequence becomes $(1, 3, 2, 4, 5)$, which should be printed.

Sample Input 2

7 1 1

Sample Output 2

1 2 3 4 5 6 7

It is possible that $L = R$.

Sample Input 3

10 1 10

Sample Output 3

10 9 8 7 6 5 4 3 2 1

It is possible that $L = 1$ or $R = N$.
