Developer Francis' Code Review Enthusiasm

Every developer has experienced this. You spend hours debugging your code, checking every function, rewriting logic… and the real problem ends up being a tiny mistake. Sometimes the biggest lessons in programming come from the smallest bugs. Read the story: https://lnkd.in/dTF-2uV7 #programming #webdevelopment #coding #softwareengineering

Why everything looks correct isn't enough ? I was solving a leetcode problem today.I thought I had it all figured out because the logic was perfect and it worked on almost every test case. I converted the array elements into a number, manipulated it, and then converted back. On paper, it seemed fine until a few edge test cases failed. The reason was integer overflow. My "correct" solution was fundamentally flawed. #DSA #LeetCode #CodingLessons #ProblemSolving #Programming #LessonLearnt

I wrote a beginner-friendly article explaining 10 Pattern Problems in C++ with diagrams and code. Pattern problems are a great way to improve logic and understanding of loops. Check it out here: https://lnkd.in/grVA7Ggb #Programming #CPP #Coding

They said it couldn't be tested... But they were wrong. Sort of. We're done with excuses! No more claims that when dealing with legacy code your changes can't be tested. We're drawing the line now. It's true that some code really just doesn't lend itself well to being tested. There's no denying that! But what if we could guarantee that every time we touched some code, even in the most untestable places, that we could do *SOMETHING* that added a bit more test coverage to build confidence?

Design HashSet: https://lnkd.in/gAJKquxc My Solution: Time Complexity: O(N) --Worst Case Space Complexity: O(N) Can be improved with Rehashing #LeetCode #DSA #ProblemSolving #CPP #Programming #Coding #Solution #Hashing #LinkedList

Funny thing about coding: You don’t spend most of your time writing code. You spend it trying to understand why the code you wrote yesterday… worked yesterday. Half of development is logic The other half is detective work 🔍 Anyone else had a bug magically disappear after adding a console.log()? #programming #developerlife #coding #tech

WORD OF THE DAY : STACK OVERFLOW What it means: A Q&A platform where developers ask and answer programming questions. Also refers to when a program runs out of memory in the call stack. Example: "I was stuck on a bug for hours until I found the solution on Stack Overflow." #Programming #Coding #StackOverflow #DevTips #LearnToCode #devwordoftheday

🚀 Implemented Insertion Sort today! It sorts the array by picking an element and inserting it into its correct position in the sorted part. 💻 Simple logic, great for small or nearly sorted data. Time Complexity: O(n²) #InsertionSort #DSA #Coding #Programming

Solved “Binary Tree Preorder Traversal” on LeetCode today using an iterative approach in C++. Key focus areas: Stack-based traversal instead of recursion Optimizing traversal order (push right child first, then left) Clean handling of edge cases (null root) Result: 100% runtime performance Efficient memory usage #LeetCode #DataStructures #Algorithms #DSA #BinaryTree #TreeTraversal #Cpp #Programming #SoftwareDevelopment #CodingJourney #ProblemSolving #ComputerScience #DeveloperGrowth

You know that feeling when you need to dive into a new codebase and it's completely overwhelming? We've all been there starting on a new project. It's all new. You have no idea where to start looking to understand the complexities of the code and the system in front of you. Sometimes there's documentation, sometimes not. Sometimes there's existing expertise, sometimes not. What can we do to try and optimize our approach? Check out the article: https://lnkd.in/gps5GWZ7 #coding #programming #softwaredevelopment
