Construct Minimum Bitwise Array II: LeetCode Problem Solving

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

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

I compared iterative and recursive implementations of Fibonacci in C++. The loop-based version runs in linear time with constant memory. The recursive version is elegant but exponentially slow due to repeated calls. This clearly shows why simplicity in code does not always mean efficiency. In real-world C++, performance-friendly designs matter more than elegance. #CPlusPlus #Programming #Algorithms #Performance #SoftwareEngineering #CppLearning #Coding

A function in C is a block of code that performs a specific task and can be reused. Basic structure: return_type function_name(parameters) { // function body } Example: int add(int a, int b) { return a + b; } How to use it: int result = add(10, 20); #CProgramming #LearnC #ProgrammingBasics #FunctionsInC #Coding

Today, I came across a random post on LinkedIn that showed a small function called getValidInput() for taking integer input from the user. The code included two things: cin.clear() and cin.ignore(). int getValidInput() { int x; while (!(cin >> x)) { cin.clear(); cin.ignore(1000, '\n'); cout << "Invalid input! Enter numbers only: "; } return x; } Surprisingly, both of these were new to me. For the past 7–8 years, I’ve been handling this using my own function built purely on core logic. It’s interesting how you can work for years and still discover something new. Check out my code😁 #logic #programming

Data Structures problem: MAXIMUM PRODUCT SUBARRAY Given an array with positive, negative numbers and zeros, find the maximum product from any continuous subarray. At first it looks simple… multiply numbers and keep the largest, right? But the twist is negative numbers. Example: [-2, 3, -4] → answer is 24 because 3 × (-4) = -12, then -12 × (-2) would have been big if order changed. #DSA #Programming #DynamicProgramming

Leetcode POTD: Find Smallest Letter Greater Than Target Intuition: My first thought was simple: sort the array and look for the smallest character that is strictly greater than the target. After sorting, I linearly scan the array and return the first character that satisfies this condition. Optimized Approach: Since the array is sorted, using binary search makes more sense. Binary search helps us directly find the smallest character greater than the target in O(log n) time. If no such character exists, we simply return the first character to handle the wrap-around case. Efficient, clean, and optimal ✨ #leetcode #potd #problemsolving #programming #consistency

C – Function Prototypes I used to think function prototype in C were just Formatting. Something like: int sum (int, int); As C compiler reads code from top to bottom. The main() calls sum(a, b), the compiler must already know: – Does this function exist? – What does it return? – What parameters does it expect? THAT’S where Prototype provides- the function signature before its definition. Without it, the compiler has incomplete information and may throw errors or assume incorrectly. So, to avoid mistakes understanding this changed how I see C. It’s about clearly communicating with intent to the compiler before execution ever happens. > Small detail.

In C++, some standard library algorithms provide counted overloads that take a begin iterator plus a number of elements. With C++20, std::counted_iterator adapter generalizes this pattern, making any algorithm usable as a counted variant. --- ♻️ 𝑅𝑒𝑝𝑜𝑠𝑡 𝘢𝑛𝘥 𝐹𝑜𝑙𝑙𝑜𝑤 Mehdi Sagar 𝑖𝑓 𝑦𝑜𝑢 𝑎𝑟𝑒 𝑖𝑛𝑡𝑒𝑟𝑒𝑠𝑡𝑒𝑑 𝑖𝑛 𝘴𝑖𝘮𝑖𝘭𝑎𝘳 𝑡𝑜𝑝𝑖𝑐𝑠. #cpp #cplusplus #moderncpp #cpp17 #cpp20 #cpp23 #coding #code #programming #named #parameter #array #typesafety #tech #future #embedded #software #iterator #cleancode #ranges #views #memorysafety
