🍁 Understanding Design Patterns: Observer Pattern Let’s look at the Observer Pattern. This pattern allows an object, known as the subject, to maintain a list of its dependents, called observers, and notify them automatically of any state changes. It's particularly useful for implementing event-handling systems and monitoring state changes in distributed systems. ⏮Adapter Pattern ⏭Stay tuned for the next post! #DesignPatterns #ObserverPattern #SystemDesign #LowLevelDesign #SoftwareEngineering #BackendDevelopment #Programming #Coding #Java #Python #TechTips #CodingTips #CareerAdvice #TechCareers #Hiring #JobSearch #ITJobs #SoftwareJobs #SeniorDeveloper #TechInterviews #python #Java

🍁 Understanding Design Patterns: Factory Pattern Let’s look at the Factory Pattern. This pattern provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created. It's useful for managing and encapsulating the creation process, especially when the exact type of object to be created isn't known until runtime. ⏮Builder Pattern https://lnkd.in/gSfBYXwF ⏭Stay tuned for the next post! #DesignPatterns #FactoryPattern #SoftwareEngineering #BackendDevelopment #Programming #Coding #Java #Python #TechTips #CodingTips #CareerAdvice #TechCareers #Hiring #JobSearch #ITJobs #SoftwareJobs #SeniorDeveloper #TechInterviews

#3/365 What is the Palindrome Number Problem? The Palindrome Number problem is an easy level algorithmic challenge frequently asked in coding interviews. The problem statement is as follows: Given an integer x, return true if x is a palindrome integer. An integer is a palindrome when it reads the same backward as forward. For example, 121 is a palindrome while 123 is not. Approaches to Solve: 1) String Conversion Approach: Time Complexity: O(n), where n is the number of digits in the integer. Space Complexity: O(n) Explanation: Convert the integer to a string and check if the string is equal to its reverse. This method is straightforward but not the most efficient in terms of space. So, I used reversing the integer approach 2) Reversing the Integer Approach: Time Complexity: O(n) Space Complexity: O(1) Explanation: Reverse the entire integer and compare it with the original integer. This approach avoids extra space usage and directly works with the integer. Explanation of the Reversing the Integer Solution Step 1: Store the original integer value in a temporary variable (temp). Step 2: Initialize a variable rev to store the reversed integer. Step 3: Use a loop to reverse the integer: Extract the last digit of temp using the modulus operator (temp % 10). Append this digit to rev by multiplying rev by 10 and adding the extracted digit. Remove the last digit from temp by dividing it by 10. Step 4: Compare the original integer (x) with the reversed integer (rev). If they are equal and x is non-negative, the number is a palindrome. Using the reversing the integer approach allows us to solve the problem without extra space for string conversion. It directly manipulates the integer, ensuring optimal space complexity. This approach also provides a clear and intuitive method for checking palindromes. Looking forward to tackling more challenges and refining my coding skills. #LeetCode #Java #Coding #Algorithms #DataStructures #ProblemSolving #Palindrome #Programming #Java #Tech
