🔍Day 7 of #100DaysOfLeetCode: Single Number Today, I tackled the "Single Number" problem on LeetCode! The goal was to find the single unique element in an array where every other element appears twice, achieving a solution with linear runtime and constant space complexity. Approach: The solution uses the XOR bitwise operator, taking advantage of the property that x ^ x = 0 and x ^ 0 = x. By XOR-ing all the numbers together, duplicate elements cancel out, leaving only the single unique number in the array! #LeetCode #CodingChallenge #SingleNumber #BitwiseOperations #PythonProgramming #DataStructures #Algorithms #100DaysOfCode #TechSkills #ProblemSolving #LinearComplexity

Day 72: Unique Number and Maximum Product Today’s challenges focused on array manipulation and optimization. The first problem, "Single Number," required identifying the only number in an array that appears once, while every other element appears twice—a fun application of bitwise operations. The second, "Maximum Product Subarray," involved finding the contiguous subarray with the largest product, which tested my ability to handle negative numbers and zero efficiently. These problems helped improve my understanding of bit manipulation and dynamic subarray handling. Problem Links:- 136. Single Number:- https://lnkd.in/gtZYKCXG 152.

Day 120 of #180DaysOfCode: Power of Four 🌟 Day 6/10 of Bit Manipulation Today's challenge was about determining whether a given integer is a power of four. This problem was an excellent way to reinforce my understanding of bit manipulation and number theory. To solve it, I checked if the number has only one set bit in its binary representation and ensured that the set bit is in an even position (since powers of four have their 1-bit in positions like 1, 4, 16, etc.). This approach allowed me to achieve an efficient solution using bitwise operations. This problem was a fantastic exercise in recognizing binary patterns and applying them to solve algorithmic challenges. Excited to continue diving into more bit manipulation problems! 🚀 #180DaysOfCode #PowerOfFour #BitManipulation #CodingJourney #ProblemSolving #Tech #ContinuousImprovement #Algorithms

Day 127 of #180DaysOfCode: Single Number II 🌟 day 9/10 of bit manipulation Today, I worked on the "Single Number II" problem, where the challenge was to find the number that appears exactly once in an array, while every other number appears three times. 🔄✨ To solve this problem, I used a bitwise manipulation approach that efficiently tracks the frequency of each bit across all numbers in the array. By counting the number of times each bit is set, I identified the bits corresponding to the unique number. Any bit count that is not divisible by three corresponds to the bits of the single number. This problem was a great opportunity to deepen my understanding of bitwise operations and reinforce my skills in solving problems with optimal time complexity! 🚀💻 #180DaysOfCode #SingleNumberII #BitwiseManipulation #Optimization #ProblemSolving #Tech #Algorithms

🎯 Challenge Completed - Day 158 🎯 Today’s LeetCode challenge was solving "Neighboring Bitwise XOR", a clever problem that combines bitwise operations and logical deductions. 🚀 📘 Problem Overview: Given a derived array, the task was to determine if there exists an original array such that the XOR of each neighboring pair in original produces the corresponding value in derived. 💡 Approach and Insights: 1️⃣ Key Observations: For an array original, if derived[i] = original[i] XOR original[i+1], the cumulative XOR across all values in derived must be zero for a valid original array to exist. This is because XOR is both associative and self-canceling when applied in a loop. 2️⃣ Algorithm Breakdown: Step 1: Initialize xor_sum to 0. Step 2: Traverse through the derived array and compute the XOR of all elements. Step 3: Check if the cumulative XOR (xor_sum) equals 0. If so, return True (valid original array exists); otherwise, return False. 3️⃣ Complexity Analysis: Time Complexity: O(n), where n is the length of the derived array. Space Complexity: O(1), as we use a single variable to store the XOR result. 📊 Key Takeaways: This problem demonstrates the power of XOR in validating conditions without explicitly reconstructing arrays. The XOR operation’s properties make it a highly efficient tool in array and bitwise problems. 🛠️ Problem-Solving Skills Improved: Understanding XOR's associative and canceling properties. Recognizing patterns to simplify logical conditions. Optimizing solutions for problems involving large arrays. #Day158 #LeetCodeChallenge #NeighboringBitwiseXOR #BitwiseOperations #AlgorithmDesign #CodingSkills #EfficientAlgorithms #PythonProgramming #DailyCoding #TechJourney #ProgrammingPractice #LeetCodeSolutions #LearnToCode #ProblemSolvers #ChallengeYourself #CodingJourney #CodeImprovement #AlgorithmicThinking #SoftwareEngineering #ProgrammingLife #CodeLearning #LogicalThinking #CodingIsFun #LeetCodeDaily
