The Biggest Mistake Students Make With Hash Tables

Picture this: you're grinding through homework, and suddenly a Hash Tables question brings you to a dead stop. It's frustrating, but the fix is actually simpler than you think.

Did you make this error?

• The Trap: failing to account for collision resolution
• The Proof: Read this scenario: If you hash 'Apple' and 'Banana' and they both result in index 4, you can't just overwrite the data. You must use chaining or linear probing.

If your logic doesn't match the proof above, you've fallen for the trap. Erase it and start over.
