LeetCode #11 - Container With Most Water Two Pointer Approach | Time Complexity: O(n) linear time complexity This problem is a great example of how the Two-POinter technique can turn an O(n^2) brute force approach into an efficient O(n) solution. The Idea: 1. Start with two pointer at both ends 2. Move the smaller height pointer inward 3. Keep track of the maximum area #LeetCode #DSA #Coding #programming #ProblemSolving #TwoPonters #CPP #Prepration #DataStructure #Algorithm #LateNight

📅 Day 35 of #100DaysOfCode Problem: Search in Rotated Sorted Array II (LeetCode 81) Approach: 1️⃣ First, handled duplicates by skipping consecutive equal elements from both ends to avoid confusion while finding the rotation point. 2️⃣ Used a modified binary search to find the pivot (the smallest element’s index) — this separates the rotated parts of the array. 3️⃣ Performed binary search on both halves — before and after the pivot — to check where the target lies. 4️⃣ Returned true if found in either part, else false. #100DaysOfCode #LeetCode #BinarySearch #RotatedArray #ProblemSolving #Algorithms #DSA #Cplusplus #CodingChallenge #Programming #DeveloperLife #CodeNewbie #DailyDSA #TechCommunity #KeepLearning #SoftwareEngineering #LearningInPublic #Motivation

📅 Day 48 of #100DaysOfCode Problem: Search in Rotated Sorted Array II (LeetCode 81) Approach: 1️⃣ First, used a pivot function to find the smallest element’s index, skipping duplicate values on both sides. 2️⃣ Once the pivot was found, split the array into two sorted parts. 3️⃣ Applied normal binary search on both halves to find the target. 4️⃣ Combined both steps to handle rotations and duplicates efficiently. #100DaysOfCode #LeetCode #DSA #ProblemSolving #BinarySearch #Cplusplus #CodingChallenge #Algorithms #Programming #DeveloperLife #CodeNewbie #SoftwareEngineering #CodingJourney #DailyDSA #KeepLearning #TechCommunity #GrowthMindset #Motivation

📅 Day 32 of #100DaysOfCode Problem: Design HashSet (LeetCode 705) Approach: 1️⃣ Used a boolean vector of fixed size (1,000,001) to represent presence or absence of elements directly by index. 2️⃣ add(key) marks the key as true, meaning it’s present in the set. 3️⃣ remove(key) simply resets the value to false. 4️⃣ contains(key) checks presence in O(1) time using direct indexing — super efficient and clean! #100DaysOfCode #LeetCode #DSA #ProblemSolving #Cplusplus #CodingChallenge #HashSet #DataStructures #Algorithms #CodeNewbie #Programming #DeveloperLife #SoftwareEngineering #LearningInPublic #TechCommunity #KeepLearning #CodingJourney #Motivation #Efficiency

🔥 LeetCode POTD: Number of Substrings With Only 1s Today’s question was actually on the easier side… once you notice the key detail: it’s a binary string 👀. Here’s how my thought process went ⬇️ At first, I considered generating all substrings and then checking which ones contain only 1s. But of course… generating + checking = ❌ higher time complexity, which breaks the constraints. Not ideal. Then I took a step back and realized: 👉 Since it's a binary string, the substrings made of only 1s form clear continuous blocks. 👉 For each block of consecutive 1s of length k, the number of valid substrings is: k × (k + 1) / 2 ✨ Using this pattern, the whole problem can be solved in O(n) time. Dropped my solution in the image below 📸 Would love to hear how you approached it! 😄💬 #leetcode #leetcodechallenge #dsa #coding #programming #problemsolving #binarystrings
