📚 Searching Algorithms | Searching Algorithms Linear Search, Binary Search, BST Search, and Interpolation Search 📌 Key Formulas: 1. Linear Search — O(n): Time: O(n) worst/avg, O(1) best | Space: O(1) 2. Binary Search — O(log n): Time: O(log n) | Space: O(1) iterative, O(log n) recursive | Requires sorted input 3. BST Search — O(log n) Average: Time: O(log n) avg (balanced), O(n) worst (skewed) | Space: O(log n) recursive 4. Interpolation Search: Time: O(log log n) avg (uniform), O(n) worst | Requires sorted + uniform data ⏱️ Timestamps: 0:00 Introduction 0:29 Linear Search — O(n) 1:06 Binary Search — O(log n) 1:45 BST Search — O(log n) Average 2:22 Interpolation Search 3:07 Linear Search for Element 3:33 Binary Search Step-by-Step 4:07 Search in a BST 4:38 Compare Search Algorithms 5:21 Quick Tips & Tricks | टिप्स 5:50 Summary | सारांश 💡 Quick Tips: • Binary search requires sorted input — if not sorted, sort first in O(n log n) then search • For GATE: binary search comparison count = ceil(log2(n+1)) — remember the plus 1 • BST search only O(log n) if balanced — use AVL or Red-Black tree for guaranteed balance • Interpolation search shines on uniformly distributed data — phone book is the classic analogy 📚 Useful for: GATE CSE, Placements, Coding Interviews and all govt exams ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📱 Download App: https://play.google.com/store/apps/details?id=com.selectionwithsathi.app 🌐 Website: https://selectionsathi.com 🔔 Subscribe: https://www.youtube.com/@SelectionWithSathi #SelectionSathi #SearchingAlgorithms #GovtExam #SSC #Railway #सरकारीपरीक्षा
