1. Extract stopwords, positive words and negative words from the given website and create 3 Tries for each of them.
2. Initiate a loop to read each article while removing stopwords.
3. Create two lists for the positive words and negative words extracted to be stored in.
4. Calculate positivity for each country.
5. Plot graphs for the output
Types of graphs: Bar chart/ Table/ Pie chart

1. Import local centers for each country from the dataset in the csv file given 
2. Call TomTom API to get the distance and route from one location to another
3. Create a distance matrix from one location to all other locations for all locations
4. Find distribution centre as the most central located store (i.e shortest total distance)
5. Run 2-Opt algorithm to optimize the delivery route
6. Create Folium Map and Plot Markers for distribution centre and other local stores
7. Draw route lines with route data from TomTom Api

1. Get the probability of a country having good economic and social condition by using the output of problem 1 (positive words, neutral words and negative words)

2.  Get the probability of a country having optimum delivery system by using the output from problem 2 (the optimum delivery distance of the countries)

3. Calculate the probability of a country to be recommended to have expansions by using the outputs got from step 1 and step 2. 

4. Our idea of the formula for the calculation in step 3 is to implement the concept of probability in which we multiply the output in step 1 with the output in step 2. 
(probability of a country having good economic and social condition  * probability of a country having optimum delivery system)

5. Then we modify the formula to :
[probability of a country having good economic and social condition  * ( 1 - probability of a country having optimum delivery system) ]

6. After getting the probability of a country to be recommended to have expansions, we use Quicksort algorithm to rank the countries from most recommended to least recommended.
