Gamify the DSA Learning Experience with Challenges

[gautamankoji]

Issue: Help us create a folder of DSA challenges! These challenges should be unique problems that test different DSA concepts, and can be used by others to practice their skills.
Requirements:

• Create a markdown file with the challenge description.
• Include a solution in your language of choice (e.g., Python, C++, Java).
• Provide a detailed explanation of the thought process and how DSA concepts were applied.
• Bonus: Add a visual explanation using diagrams or pseudocode!

Suggested Challenge Topics:

• Graph Traversal: Find the shortest path in a city grid.

• Dynamic Programming: Solve a stock-buying problem for maximum profit.

  Help learners practice DSA with fun and challenging problems!
