#Dsa Problems And Solutions In Python

Day 2 : of learning, DSA with Python Comment “list” and I will send you the notes Will learn about stacks in day 3 #programming #coding #programminglife

Comment "CODE" if you want the clear Brute Force and HashMap code with full explanation PDF. 🔥 Day 1 of 100 Days LeetCode DSA Challenge 🚀 Problem: Two Sum Most beginners solve this using Brute Force, which takes O(n²) time because we check every pair. But in this video, I explained how to optimize it using HashMap and reduce the time complexity to O(n). ⚡ This is how top programmers think — first brute force, then optimize. If you are starting DSA, this is the most important problem to understand HashMap concept clearly.

My 2026 DSA Learning Planner (pattern-wise) If I have to start DSA this is how my planner would look like 🫶🏻 📌 Month 1 – Basics Arrays, Strings, Binary Search, Two Pointers, Sliding Window 📌 Month 2 – Core DS Linked List, HashMap, Stack, Heap 📌 Month 3 – Trees & Graphs Binary Tree, BST, Graphs 📌 Month 4 – Advanced Dynamic Programming, Greedy, Trie No random practice. Only interview-relevant patterns. Want to learn all these pattern-wise? Here’s my complete DSA sheet – RV Sheet 📄 💬 Comment “LINK” and I’ll send it to your DMs. Follow for structured DSA prep 💯

𝐇𝐨𝐰 𝐦𝐮𝐜𝐡 𝐃𝐒𝐀 𝐢𝐬 𝐞𝐧𝐨𝐮𝐠𝐡 𝐭𝐨 𝐜𝐫𝐚𝐜𝐤 𝐌𝐢𝐜𝐫𝐨𝐬𝐨𝐟𝐭, 𝐆𝐨𝐨𝐠𝐥𝐞 𝐨𝐫 𝐖𝐚𝐥𝐦𝐚𝐫𝐭? This is the most common DM which I get from juniors are, “Ma’am, I’ve solved 300+ questions but still can’t solve new ones. How many do I really need to do?” Here’s the truth it’s not about the count, it’s about the patterns. Once you master patterns, every new problem feels familiar. Here are the 15 patterns you must know for placements: 1. 𝐓𝐰𝐨 𝐏𝐨𝐢𝐧𝐭𝐞𝐫 𝐓𝐞𝐜𝐡𝐧𝐢𝐪𝐮𝐞 – Solve pair/relationship problems in arrays/linked lists. 2. 𝐒𝐥𝐢𝐝𝐢𝐧𝐠 𝐖𝐢𝐧𝐝𝐨𝐰 – Efficiently handle subarray/substring problems. 3. 𝐇𝐚𝐬𝐡𝐢𝐧𝐠 / 𝐅𝐫𝐞𝐪𝐮𝐞𝐧𝐜𝐲 𝐂𝐨𝐮𝐧𝐭𝐢𝐧𝐠 – O(1) lookups for counts, duplicates, mapping. 4. 𝐏𝐫𝐞𝐟𝐢𝐱 𝐒𝐮𝐦𝐬 – Answer range queries fast. 5. 𝐁𝐢𝐧𝐚𝐫𝐲 𝐒𝐞𝐚𝐫𝐜𝐡 (𝐚𝐧𝐝 𝐯𝐚𝐫𝐢𝐚𝐧𝐭𝐬) – For sorted arrays or monotonic conditions. 6. 𝐆𝐫𝐞𝐞𝐝𝐲 – Local choices that lead to global solutions. 7. 𝐃𝐲𝐧𝐚𝐦𝐢𝐜 𝐏𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐢𝐧𝐠 – Break down overlapping subproblems. 8. 𝐁𝐚𝐜𝐤𝐭𝐫𝐚𝐜𝐤𝐢𝐧𝐠 – Explore all possibilities (subsets, permutations). 9. 𝐁𝐅𝐒 – Shortest paths, level-by-level traversals. 10. 𝐃𝐅𝐒 – Explore all paths, detect cycles. 11. 𝐇𝐞𝐚𝐩 / 𝐓𝐨𝐩-𝐊 – Manage largest/smallest efficiently. 12. 𝐌𝐞𝐫𝐠𝐞 𝐈𝐧𝐭𝐞𝐫𝐯𝐚𝐥𝐬 – Handle overlaps in schedules. 13. 𝐔𝐧𝐢𝐨𝐧-𝐅𝐢𝐧𝐝 – Manage connectivity in graphs. 14. 𝐓𝐫𝐢𝐞 – Prefix-based search and storage. 15. 𝐌𝐨𝐧𝐨𝐭𝐨𝐧𝐢𝐜 𝐒𝐭𝐚𝐜𝐤 / 𝐐𝐮𝐞𝐮𝐞 – Solve next/previous greater/smaller problems. And remember, DSA is not a sprint, it is a marathon. Rejections will happen, and that is normal. But every attempt makes you sharper, and every failure teaches you a pattern in life too. #DSA #Placements #CodingInterviews #ProblemSolving #CareerAdvice #DSA #DataStructures #Algorithms #CodingInterview #LeetCode #HackerRank #Codeforces #CodeSignal #ProblemSolving #BigONotation #SystemDesign #TechCareers #InterviewPreparation #FAANG #SoftwareEngineering #CodingLife #ProgrammersLife #CareerGrowth #ComputerScience

Cracking coding interviews isn’t about solving hundreds of random problems, it’s about recognizing patterns. Most problems can be reduced to a handful of problem-solving patterns. Once you master them, most new problems will feel familiar, just with a twist. Here are the must-know DSA patterns with common use cases & examples (Part-1) [ Check out Part-2 on my profile ] 👉 Save this as your go-to checklist before interviews!
