Hello, again 

Today, I finished the remaining rooms in the Pre-Security Pathway. I reviewed programming concepts and the CIA triad, and I can finally focus on the network analysis rooms.

I also solved several interactive challenges involving the Caesar cipher to demonstrate symmetric encryption, and they were genuinely fun to work through.

Next, I was almost able to complete the speller code, but it still suffers from low performance because I have not yet improved the hash function, which I will work on tomorrow.

I am using a hash table with linked lists for collision handling. Currently, it takes O(n) time in practice due to poor distribution. Collisions are handled using chaining, where each bucket stores a linked list. However, I am only using 26 buckets, and the hash function returns a value based solely on the first character of the word. Each new node is prepended to the list.

As a result, lookups require linear traversal through long linked lists, which significantly impacts performance. Tomorrow, I will work on improving the hash function and compare the results.

#Day45 of #100HappyDays / #365HappyDays saw me at police HQ again delivering another session to ACR staff. Again the session was interactive, they were well engaged, and the feedback was really really positive.

Definitely happy with that.
