Description: 
        Data Structures and Algorithms
        ==============================
         
        This repository contains my implementations of data structures and algorithms using Python 3. Most of the algorithm questions are taken from LeetCode. This is a work in progress.
        
        ## Install
        You can use this as an API in your code as follows:
        
            $ pip3 install algorithms3
        
        An example of running an algorithm:
        
        ```python3
        #Check if a string containing brackets is valid or not
        
        from algorithms.stack import validate_parantheses
        
        if __name__ == '__main__':
            test = validate_parantheses('()[]')
            print(test)
        ```
        
        If an algorithm is listed in this repository but is not in the pip package, it means that I have not uploaded the latest version. I will be doing that once a week. 
        
        ## Uninstall
        If you want to uninstall, simply run:
        
            $pip3 uninstall algorithms3
        
        ## Tests
        I have written basic tests for most of the modules. To run all the tests at once run the following from the base directory of the project:
            
            $python3 -m unittest discover tests
