Day 70 of #100DaysOfCode 💻 Solved LeetCode 523 – Continuous Subarray Sum using an optimized Prefix Sum + HashMap approach. 💡 Key Insight: If two prefix sums have the same remainder when divided by k, the subarray between them is divisible by k. ⚡ Reduced time complexity from O(n²) → O(n) #leetcode #coding #dsa #cpp #programming #placements

Last week, I was telling a friend about how great it would be to customize those Claude Code loading verbs that randomly appear after you prompt. Turns out I wasn’t the only one thinking this, since Anthropic actually made them configurable earlier this year. You can customize them entirely at a system, user, or project level via settings.json files (docs link in the comments). So naturally, I had to make a list of 100+ loading messages that would give any developer a mini heart attack when read. What would you customize yours to be? #claudecode #programming #softwaredeveloper

Subtree of another tree Approach: If subRoot is null - return true If root is null - return false If values match - check isIdentical(root, subRoot) If identical - return true Else - check left and right: isSubtree(root.left, subRoot) isSubtree(root.right, subRoot) Return true if found anywhere, otherwise false TC: O(N*M) -- n =no. of nodes in root, m = no. nodes in subRoot (worst case) SC: O(h) -- height of tree ( O(N) -- skewed tree || O(logN) -- balanced tree) #coding #programming #DSA #Consistency #Leetcode #CodingJourney

Why use #If False instead of comments in Xojo? 🤔 Because it lets you keep broken, unfinished code in your files without stopping the compiler, and it makes managing nested comments a breeze. It's a simple directive with major workflow benefits. Learn more: https://lnkd.in/gAmY6fwR #Xojo #Programming #CodeQuality #TipsAndTricks

🔀 Return codes hide your algorithm. Exceptions set it free. Look at a function full of return code checks. Somewhere inside all that nesting is the actual logic but you're reading two things at once. What happens when it works, and what happens when it doesn't. That's the real cost of return codes. They force two concerns into one structure, and neither one is readable on its own. Now look at the same function with exceptions: ✅ Verify the session ✅ Resolve the channel ✅ Moderate the content ✅ Broadcast to members Four steps. That's what the function does. The algorithm doesn't know about error handling. The error handling doesn't know about the algorithm. You can read either one without the other getting in the way. #CleanCode #Flutter #Dart #CodeQuality #SoftwareEngineering #Programming #DevTips #100DaysOfCode

Binary Tree Zigzag level order Traversal Approach: Do normal level order traversal Keep a boolean leftToRight ( initialize with true ) For each level: If leftToRight - push values normally (from left) Else - push in reverse order (from right) Flip direction after each level ( leftToRight = !leftToRight ) #DSA #programming #coding #problem

Ever needed to parse a binary file format or call a native API that expects raw bytes? What did you reach for: MemoryBlock, Ptr, or something else? #LowLevel #Programming

Real talk: You keep adding console logs but still can’t find the issue. Too much noise. No direction. Fix: - Log specific values only - Trace one flow at a time - Remove useless logs Good debugging is focused. #Programming #Debugging #DevTips #WebDev

Day 12 of 30 — async/await looks simple. These 3 mistakes prove it isn't 😬 Pitfall 1 → async void (exceptions disappear) Pitfall 2 → .Result / .Wait() (deadlock risk) Pitfall 3 → missing ConfigureAwait(false) in library code Before/after fixes for all 3 in the image 👇 Which of these have you run into? Be honest 👇 #CSharp #AsyncAwait #DotNet #Programming #SoftwareEngineering
