Decrement OR Increment

Write a program to obtain a number N$N$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 N.

Output:

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

Constraints

• 0≤N≤1000$0\le N\le 1000$

Sample Input:

5

Sample Output:

4

EXPLANATION:

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

SOLUTION USING C LANGUAGE:-

#include <stdio.h>
int main(void) {
    int N;
    scanf("%d",&N);
    if(N%4==0)
    N=N+1;
    else
    N=N-1;
    printf("%d",N);
	// your code goes here
	return 0;
}
