Day 1 - Code Java Smart | Check for Prime Number

Welcome to Code Java Smart, where we explore efficient and optimized approaches to Java programming! In today's video, we dive into a faster way to check if a number is prime using the 6k ± 1 optimization. Why This Approach? Instead of checking every number up to √n, we only check numbers in the form 6k+1 or 6k+5, since prime numbers greater than 3 cannot be divisible by 2 or 3. This reduces operations and improves performance by 3x compared to the traditional method! In This Video, You’ll Learn: ✅ How prime numbers follow the 6k ± 1 pattern ✅ Why we only check numbers up to √n ✅ How this approach optimizes performance ✅ Implementation in Java with step-by-step explanation Study resources : https://github.com/Jain131102/Code-Ja... https://www.geeksforgeeks.org/problem... https://www.geeksforgeeks.org/quick-w...
