10584: ABC356 —— A - Subsegment Reverse
[Creator : ]
Description
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.
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.
Input
The input is given from Standard Input in the following format:
```
$N$ $L$ $R$
```
```
$N$ $L$ $R$
```
Output
Let $A' = (A'_1, A'_2, \dots, A'_N)$ be the sequence after the operation. Print it in the following format:
```
$A'_1$ $A'_2$ $\dots$ $A'_N$
```
```
$A'_1$ $A'_2$ $\dots$ $A'_N$
```
Constraints
- All input values are integers.
- $1 \leq L \leq R \leq N \leq 100$
- $1 \leq L \leq R \leq N \leq 100$
Sample 1 Input
5 2 3
Sample 1 Output
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.
After reversing the second through third elements, the sequence becomes (1,3,2,4,5), which should be printed.
Sample 2 Input
7 1 1
Sample 2 Output
1 2 3 4 5 6 7
It is possible that L=R.
Sample 3 Input
10 1 10
Sample 3 Output
10 9 8 7 6 5 4 3 2 1
It is possible that L=1 or R=N.
