handling collisions. We then explored collision resolution techniques in detail, including
chaining, linear probing, quadratic probing, and double hashing, each with its strengths and
weaknesses.
We analyzed performance by introducing the concept of the load factor, showing how
it affects efficiency. We compared average-case and worst-case scenarios, demonstrating
how poor hash functions or high load factors can degrade performance. We also discussed
trade-offs in hash table design, balancing memory usage, speed, and collision resolution
strategies.
Finally, we explored applications of hashing in real-world systems: database indexing,
password storage, caching, and compiler symbol tables. These examples illustrated how
hashing underpins critical computing tasks. We concluded with the limitations of hashing,
including collision overhead, memory usage, and security concerns with weak hash functions.
Overall, hashing is a cornerstone of computer science, offering speed and efficiency
but requiring careful design to avoid pitfalls.
