Discover data structures and algorithms using Python. Gain insights into solving real-world problems and typical interview questions with detailed reviews, explanations, and hands-on coding exercises.

Data structures and algorithms are among the most fundamental concepts of Computer Science. Whether it’s real-world problems you’re trying to solve or the typical coding question asked in an interview, almost every problem requires you to demonstrate a deep understanding of data structures and algorithms. 

This course is a detailed review of some of the most common data structures and algorithms that you’ll see in interviews and your everyday work. With implementation details, thorough explanations, and hands-on coding exercises, you’ll quickly gain the confidence you need to solve any problem, no matter the situation.

Data Structures and Algorithms in Python

# Problem
 Given an array of numbers consisting of daily stock prices, calculate the maximum amount of profit that can be made from buying on one day and selling on another. 

 In an array of prices, each index represents a day, and the value on that index represents the price of the stocks on that day.

Here is the way to calculate the profit:
> Profit = Selling Price - Buying Price

Note that you need to buy the stocks before you sell them so the day (`index`) indicating the buying price should be before the day (`index`) indicating the selling price. 

Have a look at an example illustrated below:

Challenge yourself with an exercise in which you'll have to find the maximum profit generated by buying and selling stocks!
