Hash Tables

In the previous video on hashing basics, we stored numbers in our hash table through the use of a hash functions. But now, we show that other data types, such as Strings (or more complicated data structures) can also be stored and retreived using hashing. At the end of this video, there is an excellent explanation about the tradeoffs between linear probing and chaining.
