Logical operators are crucial when your code needs to make decisions. In Python, the main logical operators are and, or, and not. These are used in conditions to combine multiple boolean expressions. For example, checking if a number is between 10 and 20 uses and. Want to check if a user is logged in OR remembered? Use or. If you want the opposite
Python makes even traditionally tricky logic feel simple. A leap year occurs every 4 years, but there’s a twist: years divisible by 100 aren't leap years unless they're also divisible by 400. Using Python, this logic is easy to encode using conditional statements. It's a classic beginner problem to understand logical flow, modulo operators, and i
If you're aiming to start a career in backend development, Java is a powerful place to begin. The journey starts with mastering core Java—OOP principles, data structures, and exception handling. Then, dive into JDBC, Servlets, and frameworks like Spring Boot. Version control (Git), build tools (Maven/Gradle), and basic SQL are also essentials. Do
Whether you're a beginner or preparing for your first front-end role, certain questions will always come up. For example, "What is semantic HTML?" or "How do you differentiate between id and class?" Others might ask about HTML5 elements like <canvas> or <video>, or how HTML handles accessibility. To stand out, be ready to explain your a
Sorting algorithms are the backbone of many computer science problems, and merge sort stands out for its predictable performance. Unlike bubble or insertion sort, which degrade with larger data sets, merge sort uses the divide-and-conquer approach. It breaks down arrays into smaller chunks, sorts them, and then merges them back — efficiently and
