Rotating Strings with LeetCode Problem 796

🔥 Day 83 of My LeetCode Journey – Problem 242: Valid Anagram Today’s problem focused on one of the most classic string challenges — determining whether two strings are anagrams of each other. An anagram means both strings contain the same characters with the same frequency, just arranged differently. 💡 Concept: If two strings have identical character counts for every letter, they’re anagrams. Common approaches include: Using a frequency counter (hash map or array) Sorting both strings and comparing them directly ✅ Key Takeaways: Strengthened logic around hash maps and string frequency counting Learned efficient ways to compare large datasets of characters Reinforced time-space optimization techniques for string problems Small problems like this one help sharpen attention to detail and analytical accuracy, key skills for every programmer 🚀 #LeetCode #ProblemSolving #100DaysOfCode #DSA #Cplusplus #CodingChallenge #Anagram #Programming #LogicBuilding #LearningEveryday

💡 Day 84 of My LeetCode Journey – Problem 1614: Maximum Nesting Depth of Parentheses Today’s problem tested my understanding of stack concepts and string traversal — determining how deeply parentheses are nested in a given string. 🧠 Concept: The idea is simple yet elegant: Traverse the string character by character. Use a counter to track the number of open parentheses (. Update the maximum depth whenever the count increases. Decrease the counter when a closing parenthesis ) appears. Example: "(1+(2*3)+((8)/4))+1" → Maximum depth = 3 ✅ Key Takeaways: Strengthened understanding of parentheses matching and depth counting. Improved ability to simulate stack behavior without extra space. Reinforced skills in clean logic implementation and iteration control. Small yet powerful problems like this sharpen clarity, precision, and logical thinking 🧩 #LeetCode #ProblemSolving #100DaysOfCode #DSA #CodingChallenge #Programming #LogicBuilding #Cplusplus #DailyCoding #LearningEveryday

📅 Day 45 of #100DaysOfCode Problem: Count Operations to Obtain Zero (LeetCode 2169) 🧩 Approach: 1️⃣ Used a simple loop while both numbers are greater than zero. 2️⃣ In each step, added num1 / num2 to the count — because instead of subtracting repeatedly, we can do it in one go. 3️⃣ Took modulus to simulate the remainder after multiple subtractions. 4️⃣ Swapped numbers and repeated the process until one hit zero. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Cplusplus #CodingChallenge #Algorithms #Programming #DeveloperLife #CodeNewbie #DailyDSA #MathLogic #SoftwareEngineering #TechCommunity #KeepLearning #GrowthMindset #Motivation #CodingJourney

🌟 Day 80 of #100DaysOfCode 🌟 🔹 Solved the "Minimum Bit Flips to Convert Number" problem today! This challenge was all about using bit manipulation to count how many bits differ between two numbers. 🧠 Logic Breakdown: Use XOR (^) to find differing bits between start and goal. Count the number of 1s in the XOR result — each 1 represents a bit that needs to be flipped. A simple yet powerful application of bitwise operations! ⚙️ 💡 Key Takeaway: Bit manipulation may look tricky at first, but it’s one of the most elegant tools for optimizing problems in competitive programming. #100DaysOfCode #DSA #BitManipulation #Programming #CodeNewbie #CPlusPlus #ProblemSolving #CodingChallenge

What exactly is inside a C++ object? This doc explains the object model and its memory layout. ➜Objects hold only data members directly. ➜A hidden vptr is added for classes with virtual functions. ➜Multiple and virtual inheritance add extra pointers for base class management. ➜The vtable is global and not stored within each object. Understanding this helps write more efficient C++ code. #cpp #cplusplus #memorylayout #programming #coding #softwaredevelopment

📅 Day 33 of #100DaysOfCode Problem: Basic Calculator (LeetCode 224) Approach: 1️⃣ Parsed the string character by character, keeping track of current number, sign, and result. 2️⃣ When encountering '+' or '-', added the previous number to the result and reset the current number. 3️⃣ Used a stack to handle parentheses — pushed the current result and sign when '(' was found, then restored them after ')'. 4️⃣ Carefully computed the final result by adding the last pending number after traversal. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Stack #Cplusplus #CodingChallenge #Algorithms #Math #CodeNewbie #Programming #SoftwareEngineering #CodingJourney #TechCommunity #DeveloperLife #KeepLearning #LearningInPublic #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

📅 Day 42 of #100DaysOfCode Problem: Subsets (LeetCode 78) Approach: 1️⃣ Used backtracking to explore every possibility — either include the current element or skip it. 2️⃣ When the index reaches the end, added the current subset to the result. 3️⃣ Backtracked properly to remove elements before exploring the next choice. 4️⃣ This ensures every possible combination is covered without duplicates. #100DaysOfCode #LeetCode #Backtracking #Recursion #DSA #Cplusplus #ProblemSolving #CodingChallenge #Algorithms #Programming #DeveloperLife #CodeNewbie #DailyDSA #TechCommunity #KeepLearning #GrowthMindset #SoftwareEngineering #LearningInPublic #Motivation
