Data structures are basically two different ways of storing exactly the same set of data and as you can see they have
sort of different structures and so these are simplified examples of what data structures look like now if you 're already
familiar with data structures you might notice that the first method corresponds to the array or a list data structure. The
second method is the hash table or hash map data structure so what are algorithms one way to define what they are
would be that there are the operations we can perform on different data structures. An algorithm is basically you have a
problem you're going to solve in this case finding the shortest path from home to school and then you have systematic
instructions for solving that problem. Depending on what data structure you're using to store the data that you're
performing the algorithm on your algorithm might look slightly differently you might even have in some cases completely
different algorithms for solving the same problem.
Each person come to the party will bring sort of like a small ball with them like a ball that can fit in their hand and this ball
will have their name written on it. David will have a ball with David written on the ball and Kevin will have another ball
with Kevin written on them. This is actually a data structure that's realized in real life and this actually corresponds to the
data structure called array in computer science. To find in 98th person or finding the 98th box here would be much
harder than the linked list data structure. Each box can be in any location relative to the previous box so this first box
might be in the living room. Each partition is ten centimeters wide so you just need to find ten centimeters times ninety
seven times nine hundred seventy centimeters. YK from CS dojo explains what data structures are like on a computer
using concepts like classes objects memory and maybe even some code snippets too. Throughout this video I 'm going
to introduce you to even more data structures and this time I'll explain them in a much more technical way. YK says it's
so common for beginners to learn concepts and not actually be able to use them in real-world situations because they
have n't had enough practice.
