1. Prime Number via Command-Line Argument

This program checks if a number provided via command-line arguments is a prime number.

class PrimeCheck {
    public static void main(String[] args) {
        int n = Integer.parseInt(args[0]);
        boolean isPrime = true;
        if (n <= 1) isPrime = false;
        for (int i = 2; i <= n / 2; i++) {
            if (n % i == 0) {
                isPrime = false;
                break;
            }
        }
        if (isPrime)
            System.

Weighting Schemes in Weighted Cohen’s Kappa

Weighted Cohen’s Kappa uses specific weighting schemes (linear vs. quadratic) to measure inter-annotator agreement when categories are ordered.

Linear Weighting: Penalizes disagreements proportionally to category distance. This is suitable when graded differences are modest. Linear weights are simpler but less sensitive.
Quadratic Weighting: Penalizes larger disagreements more strongly, emphasizing severe

Machine Learning Definition and Related Fields

Machine Learning (ML) is a field of computer science that enables systems to learn from data and improve performance without being explicitly programmed.

ML Relationship with AI, Data Science, and Statistics

ML and Artificial Intelligence (AI)

ML is a subfield of AI that provides systems the ability to learn automatically.
AI focuses on building intelligent machines, while ML focuses on learning patterns from data to achieve intelligence.

Role of High Security in IoT Automation

m5) Explain the role of high-security requirements in IoT automation systems. Why is security more critical today?

IoT automation systems control physical processes, so security failures can cause real-world damage.
High security ensures that only trusted devices, users, and services can access the system.
Authentication is used to verify the identity of IoT devices and users.
Authorization controls what actions an authenticated system is allowed to perform.
Secure
