📊 Sorting in DSA (Quick Summary)

🔹 Definition: Sorting means arranging data in a particular order (ascending/descending).
🔹 Why it matters: Makes searching faster ⚡, data easier to analyze, and algorithms more efficient.

🧮 Common Sorting Algorithms

🧩 Bubble Sort → Compare & swap (Simple but slow 🚶).

⚡ Quick Sort → Divide & conquer, very fast in practice.

📚 Merge Sort → Stable, good for linked lists.

⚙️ Insertion Sort → Good for small datasets.

🏎️ Heap Sort → Based on binary heap, efficient.


✅ Tip: Always choose sorting based on data size + constraints.

So Today I was trying to beat the amazjng part of DSA which is sorting. The core thing for data organization in Machine learning. I also tried to solve leetcode problem. ግን እኔ ብቻ ነኝ ጥያቄው ገብቶኝ code መፃፍ የሚያቅተኝ:: i just know the question and know the concepts but when it comes to leetcode ወፍ. Anyways we keep learning until we understand it.

📌 Topic: Binary Search 🔍

Today’s grind is all about sharpening our Binary Search skills.
Binary Search is one of the most fundamental algorithms in coding interviews – efficient, elegant, and powerful for solving search-based problems in O(log n) time.

✨ Why it matters?

Used in searching sorted arrays & matrices 📊

Core for solving advanced problems like search in rotated arrays, peak finding, etc.

Reduces brute force and saves runtime ⚡


🔥 Your challenge for today:

Revisit the classic Binary Search template

Solve 2–3 LeetCode problems that apply it in creative ways


💡 Pro tip: Always think about the midpoint and whether to move left or right. Mastering this logic unlocks many problems beyond simple searching.

So here is all about today

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"

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 🌳😉

🚀 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
