Decrement OR Increment Codechef Solution

Hello Programmers In this post, you will know how to solve the Decrement OR Increment Codechef Solution.

One more thing to add, don’t directly look for the solutions, first try to solve the problems of Codechef by yourself. If you find any difficulty after trying several times, then you can look for solutions.

Problem

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

Input Format:

• First line will contain a number N.

Output Format:

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

Constrains

• 0 ≤ N ≤ 1000

Sample Input 

5

Sample Output 

4

Explanation:

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

Decrement OR Increment CodeChef Solutions in Python

a = int(input())
if (a % 4 == 0):
    a = a + 1
    print(int(a))
else:
    a = a - 1
    print(int(a))

Decrement OR Increment CodeChef Solutions in CPP

#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;
}

Decrement OR Increment CodeChef Solutions in JAVA

import java.util.Scanner;
public class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int N = sc.nextInt();
		System.out.println(solve(N));
		sc.close();
	}
	static int solve(int N) {
		return (N % 4 == 0) ? (N + 1) : (N - 1);
	}
}
