Document Summary
Lecture 1 - data structures and software principles. Research interests: data mining, computational geometry, computer science education. Java - learn a lot about objects and oop. Every variable has: type, name, value, and location in memory. Primitive types: bool bored; int myfavoint; char rating = "e"; double u = 37. ; ****user defined types sphere myfavosphere; a class is a group of variables (member variables) and functions associated with the class. Example of a user defined type accessing engineering workspace machine ssh jchen238@linux. ews. illinois. edu. Hash tables are a great way to access big data. Access an element via index takes a constant time of o(1) in technical terms. Yelling out and listening for right or left is a great idea, but in a practical sense, especially in said stadium, it"s difficult to hear the person. Using this method would mean that you would be able to speak to each and every single one of the attendees.
