🚀 Three Consecutive Odds – Iterative Counting Explained with a Story! 🎲🚪

Just tackled the Three Consecutive Odds problem on LeetCode! This problem challenges us to determine whether there exists any run of three odd numbers in a list, and I solved it using a straightforward Iterative Counting approach for maximum efficiency.

Story
Imagine you’re on a treasure hunt in a mystical hallway lined with numbered doors. The clue to find the treasure? Locate three odd-numbered doors standing side by side. Your map is a list of these door numbers, but they’re scrambled along the corridor.

As you walk along the hallway, you check each door. If a door number is odd, you increase your odd-door streak. But as soon as you see an even-numbered door, your streak breaks—you must start over.

If you ever hit three odd doors in a row, you unlock a secret passage (return True) and find the treasure! If you reach the end without finding three in a row, you leave empty-handed (return False).

🔹 Key Strategy:

✅ Main technique used: Iterative Counting
✅ Optimizations: Single-pass scan with constant space, early exit upon finding the streak
✅ Key learning: Simple counters can replace nested loops when looking for consecutive patterns
