Hello everyone and welcome to an Introduction to Data Structures. My name is Steven and in this lecture-style course, I’ll be taking you through the topic of #Data_Structures in relation to Computer Science. We’ll go over what Data Structures are, how we measure Data Structures' efficiency, and then hop into talking about 12 of the most common Data Structures which will come up throughout your Computer Science journey.
