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

Input:

First line will contain a number NN.

Output:

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

Constraints

0≤N≤10000≤N≤1000

Sample Input:

Sample Output:

EXPLANATION:

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

Decrement OR Increment codechef solution in C


// your code goes here
	int x;
	scanf("%d",&x);
	if(x%4==0){
	    printf("%d\n",x+1);

	}
	else if(x%4!=0)
	{
	    printf("%d\n",x-1);
	}
	return 0;
}
