Course overview
In this course, you’ll learn the fundamentals of data structures. You’ll explore linked lists and how using linked nodes is helpful in creating data structures. Then you’ll learn about queues, the FIFO data structure (first in, first out) , and the FCPS process scheduling algorithm (first come, first serve). From there, you’ll dig into stacks, LIFO (last in, first out), and LCFS process scheduling (last come, first serve) — and then dictionaries and parallel processing. By the end, you’ll understand the performance difference between data structures such as hash tables, stacks, queues, and more.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. You’ll apply this knowledge by completing two real-world data projects:
- In the first one, you’ll use stacks when implementing complex algorithms
- In the second one, you’ll analyze stock prices using hash tables and by implementing various algorithms
Key skills
- Implementing linked lists, queues, stacks and dictionaries
- Employing inheritance
- Applying data structures to solve problems
