__ Problem:-__

Write a program to obtain a number and increment its value by 1 if the number is divisible by 4 decrement its value by 1.

### Input:

- First line will contain a number .

### Output:

Output a single line, the new value of the number.

### Constraints

### Sample Input:

```
5
```

### Sample Output:

```
4
```

### EXPLANATION:

Since 5 is not divisible by 4 hence, its value is decreased by 1.

__Code:-__

#include <iostream>

using namespace std;

int main() {

int n;

cin>>n;

if(n%4==0)

cout<<n+1;

else

cout<<n-1;

return 0;

}
