Day 35/60 🚀
Solved Rat in a Maze (backtracking 🧠) and learned how to build Docker images today.
Mid-sems slowed down DSA a bit (IPU for a reason 😅), but kept the streak going.
Understanding both problem-solving and dev tools side by side

Day 31/60 🚀
Solved:
✅ Combination Sum I
✅ Combination Sum II
Key takeaways:
Backtracking = try → explore → undo (repeat)
Difference matters:
• CS I → reuse elements allowed
• CS II → no reuse + handle duplicates
