#August_30_LeetCode_Grid 📌 Graphs in DSA A Graph = 🟢 Nodes (called vertices) + 🔗 Connections (called edges). They’re everywhere — social networks, maps, recommendations, even computer networks! Types of Graphs: Directed vs Undirected ➡️ / ↔️ Weighted vs Unweighted ⚖️ Cyclic vs Acyclic 🔄 / 🚫 Ways to Store Graphs: Adjacency List ✅ (efficient) Adjacency Matrix 🔲 (easy but heavy) Popular Graph Algorithms: BFS (Breadth-First Search) 🔍 level by level DFS (Depth-First Search) 🌊 go deep first Dijkstra 🛣️ shortest path Kruskal & Prim 🌐 minimum spanning tree 👉 Mastering graphs = mastering real-world problem solving. @byte_philosopher

Happy Sunday y'all 😊 @byte_philosopher

#August_27_28_29_LeetCode_Grind HashMaps (Python dict) Recap A HashMap stores data in key–value pairs for super-fast access ⚡. Think of it like a dictionary 📖: words = keys, meanings = values. ✅ Key Features: Fast lookups, inserts, deletes → O(1) average Keys are unique Perfect for counting, mapping & caching

hashmap = {"apple": 2, "banana": 5}

print(hashmap["apple"])  # 2
hashmap["banana"] = 10   # update
hashmap["grape"] = 7     # insert
del hashmap["apple"]     # delete

🔥 Use Cases: ✔️ Word frequency counters ✔️ Caching results ✔️ Graph adjacency lists @byte_philosopher

#August_26_LeetCode_Grid 👑 Heap: The King of Efficiency 👑 Ever wondered how to always grab the biggest or smallest number FAST? ⚡ That’s where Heaps come in! 🔥 What’s a Heap? A tree-like structure 📚 Min-Heap → smallest on top (root). Max-Heap → largest on top (with a trick in Python 😉). ⚡ Why are they cool? 📍 Always gives you the top element in O(1) time. ➕ Insert / ❌ Remove in O(log n). Used in priority queues, scheduling, Dijkstra’s algorithm, and finding kth largest/smallest element! 🐍 Python Example:

import heapq

nums = [5, 2, 8, 3, 1]

heapq.heapify(nums)   # min-heap
print(nums[0])        # 👉 1 (smallest)

# max-heap trick
nums = [-x for x in nums]
heapq.heapify(nums)
print(-nums[0])       # 👉 8 (largest)

💡 Remember: Heaps don’t fully sort data, they just keep the top element ready at all times 🚀. ⚔️ Next time you need efficiency → Just call the Heap King 👑 @byte_philosopher

This days what I understand from solving leetcode is, you always have to think in the reverse way. (ገልብጦ ማሰብ😁 ) is the better way. For ex: if your first thought for the solution was addition then use substraction boom it works😁 @byte_philosopher

#August_25_LeetCode_Grid 🚀 Backtracking in DSA – Quick Recap Backtracking is like exploring all paths in a maze. You try options, go forward, and undo your choices if they don’t work. How it works: Choose: Pick a possible option. Explore: Move forward recursively with that choice. Backtrack: Undo the choice to try other possibilities. ✅ Key idea: Explore all possibilities systematically, but prune paths that fail early. ✅ Use cases: Subsets & permutations Combination sum problems Sudoku & N-Queens Maze & pathfinding problems 💡 Tips: Always have a base case to stop recursion. Make sure to undo changes before returning to explore other options. Example in LeetCode: Combination Sum, Subsets, N-Queens @byte_philosopher

Have a productive week❤ @byte_philosopher

I finished my study on trees here is the short summery

🌳 Trees in Data Structures 🌳 Think of a Tree like a family tree or folder system: 🌱 Root → the starting point 🌿 Branches (children) → connect to other nodes 🍂 Leaves → end nodes with no children ✨ Popular Trees: 🌲 Binary Tree → max 2 children per node 🔎 Binary Search Tree (BST) → left < root < right 🏗 Heaps & Balanced Trees → used in priority queues, databases ⚡ Why Learn Trees? ✔ Organize data efficiently ✔ Fast search & sorting ✔ Used in file systems, AI, compilers, HTML DOM 📌 Next time you open folders on your PC… you’re walking through a tree 🌳😉 @byte_philosopher

#August_20_LeetCode_Grind today I was just exploring what trees are and doing leetcode problems. This topic is a bit vast and with doing side projects it feels overwhelming . But here we are struggling to face the challange. Today I also noticed that I have only 2 or 3 weeks to start my 2nd year. Somehow it feels guilty when it comes to accomplishing your goal. And at the same time you need to rest but your mind can't . So here we are " we struggle to satisfy our mind and we kill the feeling of rest to feed the satsfaction for our soul"
