DSA in Python – Frog Jump | All 4 DP Approaches | Recursion to Optimal | GFG Practice | Part 192

📘 Welcome to Part 192 of Code & Debug’s DSA in Python Course!

Continuing our Dynamic Programming series after mastering Climbing Stairs—we now solve the classic Frog Jump problem from GeeksforGeeks. This is an excellent follow-up problem that builds on the Fibonacci-like pattern but introduces energy costs for jumps, making it perfect for practicing the full spectrum of DP techniques. We’ll implement all 4 approaches step-by-step, evolving from basic recursion to the most optimal space-optimized solution.

This problem reinforces key DP concepts like overlapping subproblems and optimal substructure while dealing with minimization—essential for optimization-based interview questions!

👨🏫 What’s covered in this video:
✅ Approach 1: Brute Force Recursion – Exponential time complexity
✅ Approach 2: Memoization (Top-Down DP) – O(n) time, O(n) space
✅ Approach 3: Tabulation (Bottom-Up DP) – O(n) time, O(n) space
✅ Approach 4: Space-Optimized Tabulation – O(n) time, O(1) space
✅ Complete Python code walkthrough for each approach
✅ Dry run examples with energy calculations
✅ Complexity analysis and evolution of solutions
✅ Interview tips and variations (like k-jumps extension)

By the end of this session, you’ll solidify your DP skills and learn how to apply these techniques to minimization problems!
