Lecture Description

Julie introduces hashing and it's uses in search and retrieval; map implementations and the different kinds of search algorithms are then discussed. Thereafter she explains that logarithmic searches are relatively fast and often finish the search in an immeasurable amount of time. She introduces a different approach to search that works in a faster manner than linear search.

Course Description

This course (CS 106B) is the successor to CS 106A and covers more advanced programming topics such as recursion, algorithmic analysis, and data abstraction. It is taught using the C++ programming language, which is similar to both C and Java. In the past when both CS 106A and CS106B were taught in C/C++, the coupling between the two classes was very tight and it was unheard for students to take CS106B without having completed our CS 106A (we recommended CS 106X instead). Nowadays, some students do go straight into CS106B, this is typically appropriate for a student who done well in an intro programming course (e.g., scored 4 or 5 on the CS AP exam or earned a good grade in a college course) and has sufficient familiarity with good programming style and software engineering issues (at the level of CS 106A) to use this understanding as a foundation on which to tackle advanced topics.
