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

In this lesson, we're going to determine whether or not a set of brackets are balanced or not by making use of the stack data structure that we defined in the previous lesson. 

Let's first understand what a balanced set of brackets looks like. 
   
A balanced set of brackets is
one where the number and type of opening and closing brackets match and that is also properly nested within the string of brackets. 


## Examples of Balanced Brackets
* { }
* { } { } 
* ( ( { [ ] } ) )
## Examples of Unbalanced Brackets
* ( ( ) 
* { { { ) } ]
* [ ] [ ] ] ]

This lesson will teach us how to determine whether or not a string has balanced usage of brackets by using a stack.
