Introduction Data structures form the basis for efficient programming methods and data manipulation for today’s computer scientists. They (data structures) are based upon mathematical concepts such as queues, trees, vectors, hash tables, sets etc. “Tree structures represented explicitly in computer memory were described for the first time in applications to algebraic formula manipulation by Grace M. Hopper circa 1951” The Art of Computer Programming, Fundamental Aglorithms, Vol 1, Donald Knuth, Addison Wesley 1969
Data Structures Vectors (Arrays) Stacks Queues Deques Single Linked Lists Double Linked Lists Circular Linked Lists Binary Trees Balanced Binary Trees Other Tree structures

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
