Milestone 4: Searching & Sorting Algorithms

🟦 Milestone 4: Searching & Sorting Algorithms

Arranging data and finding specific items are the most frequent tasks in computing. In this milestone, we move from “Brute Force” to “Optimized Logic.”

📚 Slow-Paced Deep Dives (University Modules)

• Module 1: Binary Search (The Phone Book): DSA-201. Finding an item in O(log n) time.
• Module 2: Sorting Basics (Bubble vs Quick): DSA-202. Understanding why O(n log n) is the “Golden Standard” for sorting.

🥅 Milestone Goals

1. Implement Binary Search on a sorted array.
2. Explain the Pivot logic behind Quick Sort.
3. Compare the time complexity of different sorting algorithms.
4. Distinguish between In-place and Out-of-place sorting.

:::tip Real World Use Your database indexes use Binary Search logic. Google’s search result ordering uses complex Sorting and ranking logic. Efficiency here saves billions of dollars! :::
