How Star Patterns Can Boost Your DSA Skills

🚀 Day 62 of #100daysChallenge 🚀 📌 Today’s Problem: Add Two Numbers (Linked List) ✅ Results: Runtime: 0 ms (Beats 💯%) Memory: 12.66 MB (Beats 74.14%) All 1563 test cases passed successfully! Key Takeaway: Today’s problem reinforced how crucial it is to understand linked list traversal and pointer manipulation. By reversing the lists first and performing digit-wise addition, we can elegantly handle carry propagation. This challenge truly strengthens both logic and precision — two pillars of clean problem-solving. 🚀 #100DaysOfLeetCode #CProgramming #LinkedList #ProblemSolving #CodingChallenge #DSA #DeveloperJourney #Consistency #KeepLearning #LeetCode

📅 Day 31 of #100DaysOfCode Problem: Reverse Pairs (LeetCode 493) Approach: 1️⃣ Divide the array using merge sort to count pairs efficiently. 2️⃣ Count cross-pairs where nums[i] > 2 * nums[j] while merging. 3️⃣ Merge the halves back in sorted order to maintain correct comparisons. 4️⃣ Sum up counts from left, right, and cross halves for the final result. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Cplusplus #CodingChallenge #Algorithms #Programming #DeveloperLife #CodeNewbie #DailyDSA #SoftwareEngineering #CodingJourney #LearningInPublic #TechCommunity #KeepLearning #DivideAndConquer #GrowthMindset #Motivation

📅 Day 49 of #100DaysOfCode Problem: 3228. Maximum Number of Operations to Move Ones to the End (LeetCode) Approach: 1️⃣ Keep a counter of how many '1's you’ve seen as you go through the string. 2️⃣ When you see a '0' that’s right before a '1' or at the end, you can “move” all those previous '1's past this '0' — so add that counter to the result. 3️⃣ Every time you hit a '1', increment the counter; for '0', check the condition and reset logic as needed. 4️⃣ Return the total operations counted — it’s just one pass through the string = O(n) time, O(1) space. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Cplusplus #Algorithms #Greedy #CodingChallenge #Programming #DeveloperLife #CodeNewbie #DailyDSA #SoftwareEngineering #KeepLearning #TechCommunity #GrowthMindset #Motivation

It's Easy To Recognise Patterns 💪 Yes it's True But we unknowingly make some mistakes We'll talk about it some other day 🙃 Today let's focus on the patterns I found in the LeetCode weekly contest 476 For in detail explain watch this yt video https://lnkd.in/gcNhp6ET Q1 : Check The expression and Find out what to be done to get the max value possible Q2 : 2 strategies 1- Look at the root level and you will find that removing adjacent values works So use stack for adjacent 2- look what's the change to the rest of the string if we remove the current substring and this will lead you to abs(cnta-cntb) formula although it has an intuition as well, which I have shared in video Q3 : It's a direct digit dp question why ?? 1- we have to make numbers by choosing digits at every position 2- the constraints are high although you can use math as well which I have talked about in the video 😅 Q4 : We have to use prefix sum but it will cause some extra stable arrays so remove them as well how we thought about the prefix and all?? 🤣 I have talked in the video as well #leetcode #contest #cf #cp #dsa #coding

📅 Day 50 of #100DaysOfCode Problem: Simplify Path (LeetCode 71) Approach: 1️⃣ Used a stringstream to split the path by '/'. 2️⃣ Ignored empty tokens and "." since they don’t change the directory. 3️⃣ For "..", popped the last directory from the stack (if any). 4️⃣ Rebuilt the canonical path from the stack in the correct order. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Stacks #Cplusplus #CodingChallenge #Algorithms #Programming #DeveloperLife #CodingJourney #CodeNewbie #DailyDSA #SoftwareEngineering #KeepLearning #GrowthMindset #Motivation #TechCommunity #CleanCode

Debugging isn’t just about fixing errors it’s about learning how to think. Each bug teaches patience, attention to detail, and the art of problem-solving. At Code1o1, we help learners see debugging not as failure, but as progress in disguise. #Code1o1 #Debugging #ProblemSolving #CodingMindset #STEMLearning

📅 Day 44 of #100DaysOfCode Problem: Minimum Number of Operations to Make Array Continuous (LeetCode 2009) Approach: 1️⃣ For each element, assumed it to be the starting point of the range. 2️⃣ Calculated what the range should end at → start + n - 1. 3️⃣ Iterated over all numbers, counted how many don’t fit in this range (those need to be replaced). 4️⃣ Kept track of the minimum replacements across all possible ranges. #100DaysOfCode #LeetCode #DSA #ProblemSolving #Cplusplus #Algorithms #CodingChallenge #Programming #DeveloperLife #CodeNewbie #DailyDSA #SoftwareEngineering #CodingJourney #TechCommunity #KeepLearning #GrowthMindset #Motivation #LearningInPublic

🚀 Day 63 of #100DaysOfCode Today I solved a C++ problem: 👉 Find K Pairs with Smallest Sums 🧩 Problem Summary: Given two sorted arrays arr1 and arr2, and an integer k, the task is to find k pairs (a, b) where a belongs to arr1 and b belongs to arr2, such that their sum is among the smallest possible. 🧠 Approach: I used a min-heap (priority_queue with greater comparator) to always extract the smallest pair sum efficiently. Start by pushing the smallest possible pairs from arr1 and the first element of arr2. Each time we pop the smallest pair, we add the next possible pair from the same row. Continue until we find k pairs. ⚙️ Key Concepts: Priority Queue (Min-Heap) Pair Sum Optimization Efficient use of STL 💡 Complexity: Time: O(k log k) Space: O(k) 👨💻 Language: C++ (STL-based) #100DaysOfCode #Day63 #CPlusPlus #STL #CodingChallenge #DSA #ProblemSolving #LeetCode #CodeNewbie #Programmer #LearnCoding #CompetitiveProgramming #cpp #DataStructures #Algorithms

On Day 285 of my #300daysofcode challenge, I'm sharing my solution to LeetCode Problem 2048, "Next Greater Numerically Balanced Number." This problem requires a focused iterative search and a helper function to verify the unique "balanced" property (where each digit $d$ appears $d$ times). My video provides a clear walkthrough of this logical method, a valuable skill for any developer and a great way to practice writing clean, reusable validation code. #DataStructures #Algorithms #LeetCode #CodingInterview #Programming #ProblemSolving #300daysofcode
