  UNDERSTANDING HAPPY NUMBERS   Introduction                       This presentation explores the concept of Happy Numbers, their properties, algorithms for determining their status, and practical applications in various fields.   What is a happy number ?                       a happy number is a number that eventually reaches 1 when replaced repeatedly by the sum of the squares of its digits. An unhappy number (also known as a sad number ) is a number that does not reach 1 and instead enters a cycle that never reaches 1.   Steps to determine if a number is happy:            1.Start with a number n .          2 . Replace n by the sum of the squares of its digits.           3. Repeat the process with the new value.    ...

  JAVA - SPRINGBOOT 1. What is Java? Java is a high-level, object-oriented programming language that is designed to be platform-independent. It follows the principle of "Write Once, Run Anywhere," which means that Java programs can run on any device or operating system that has a Java Virtual Machine (JVM). Key Features of Java : Object-Oriented : Java supports the object-oriented paradigm, meaning you can create objects that represent real-world entities. Platform Independence : Java code is compiled into bytecode, which can be run on any system that has a JVM. Multi-threading : Java supports multi-threading, which allows multiple tasks to run concurrently. 2. What is Spring Boot? Spring Boot is a framework that is built on top of the Spring Framework , which is one of the most popular frameworks for developing Java-based applications. Spring Boot simplifies the development of Java applications by making it easier to set up and run applications with minimal configurat...
