Inversion of Control Explained

When you miss a base case🧠 What is the best way to check it, what do you guys think??💬 When working with recursion, the most important step is often the simplest one: 💻Define your base case first. Before thinking about the recursive calls, pause and ask, like what’s the worst or simplest condition where the function should stop? Most of the time, that’s your base case. A small reminder from experience: 👉 Start with the base case 👉 Think about edge conditions first 👉 Then build the recursive flow Strong foundations make complex problems manageable.

🚀 Day 13/60 — LeetCode Discipline Problem Solved: Contains Duplicate II (Revision) Difficulty: Easy Today’s practice focused on revisiting a classic array problem that blends hashing with a sliding window concept. The goal was to efficiently determine whether duplicate values appear within a specific index range. Instead of checking every possible pair, the approach maintains a moving window of elements using a hash structure, allowing constant-time lookups while traversing the array. 💡 Focus Areas: • Reinforced hash-based lookup techniques • Practiced sliding window with bounded size • Strengthened index-distance reasoning • Improved understanding of time-efficient duplicate detection • Focused on clean and readable implementation Even simple problems can reinforce powerful ideas when approached with discipline and clarity. #LeetCode #60DaysOfCode #100DaysOfCode #DSA #SlidingWindow #HashSet #Arrays #Algorithms #DataStructures #ProblemSolving #CodingJourney #SoftwareEngineering #Programming #Developers

Multithreading in theory vs reality 🧵⚙️ In theory: Every thread executes independently, efficiently, and peacefully. In reality: Race conditions, deadlocks, and thread competition, context switching, synchronization issues etc. 👉 Writing multithreaded code is easy. 👉 Writing correct multithreaded code is the real challenge. #Multithreading #Programming #SoftwareEngineering #BackendDevelopment #CPP #CppProgramming #ModernCPP #Multithreading #Concurrency #ParallelProgramming #SystemProgramming #SoftwareEngineering #CodingLife

LeetCode Practice: Today I solved Problem no.328(Odd Even Linked List) Statement- We are given the head of a singly linked list , group all the node with odd indices together followed by the node of even indices , and return the reordered list. Approach(Brute Force) Key Idea: I used ana auxiliary array to store the node values 1-Traverse the list by using temp->next->next starting from head to collect the odd indexed nodes 2-Then temp=head->next and traverse it using temp->next->next to collect the even indexed nodes 3-This ensures that all the odd index were stored first followed by even indexed nodes 4- Finally convert the array into the linked list. Time Complexity: O(N) Space Complexity: O(N) (due to the extra array) #LeetCode #DataStructures #LinkedList #CodingPractice #DSA #Programming #ProblemSolving

#Day58 Solved: Longest Substring Without Repeating Characters(Leetcode 3) Worked on one of the most asked string problems that really tests problem-solving and optimization skills. Problem: Find the length of the longest substring without repeating characters. Approach: Used the sliding window technique to efficiently track a valid substring. Instead of checking all possible substrings (which is slow), I dynamically adjusted the window: Expanded when characters were unique Shrunk when a duplicate appeared Key Learning: The biggest takeaway was understanding how to maintain a valid window rather than restarting every time a duplicate is found. Complexity: Optimized the solution from O(n²) to O(n) using the right approach. This problem strengthened my understanding of: Sliding Window Two Pointer Technique Optimizing brute force solutions #leetcode #dsa #programming #coding #slidingwindow #problemSolving

Spent time today revisiting core problem-solving fundamentals. Covered arrays, time complexity and solved problems like Two Sum and Best Time to Buy and Sell Stock. What stood out: - Brute force is easy to think, but inefficient - Optimization comes from changing the way you think, not hurst coding faster - Patterns like hashing and tracking minimum values simplify problems a lot Still early in the journey, but consistency is the focus #software #softwaredevelopment #dsa #programming #learninginpublic

🚀 Day 93 of #100DaysOfCode Challenge Today’s problem was all about identifying “Beautiful Strings” 🔢✨ A numeric string is called beautiful if: ✔️ It can be split into a sequence of increasing numbers ✔️ Each number is exactly +1 from the previous ✔️ No leading zeros allowed 💡 What I Learned Today: How to break strings into valid sequences Handling large numbers using long long Importance of string comparison vs integer operations Edge cases like: Leading zeros ❌ Single digit strings ❌ Invalid increments ❌ 🧠 Approach: Try all possible starting numbers Generate the sequence dynamically (x, x+1, x+2…) Match the built string with the original If matched → ✅ YES x Else → ❌ NO 💻 Example: 👉 Input: 91011 👉 Output: YES 9 ⚡ Key Takeaway: Sometimes brute force with smart validation is the best approach! 📅 Consistency is the real game changer.

Your IDE can autocomplete your syntax, but it cannot autocomplete your logic. It is easy to get caught up in the latest plugins and the coolest themes. But at the end of the day, your brain is the compiler that matters most. A great developer can write an algorithm on a napkin if they have to. Focus on the mental models first. The tools are just there to help you type faster. Do not let the bells and whistles distract you from the actual problem solving. #Programming #DevTools #Logic #ProblemSolving

Debugging is one of the most valuable skills for developers. Sometimes the problem isn't the code. It's the assumption behind the code. #Programming #Debugging
