Calculating how many linked articles exist in both languages (for example Paris exists in both HE and EN but Elephant only exists in EN).
It should only include pages on the main namespaces not including categories.

Output:

• A matrix of (287X287 representing the different wikipedias) that counts the number of pages that exist for both languages. This matrix is symmetric.
• A matrix that presents the percentages of the overlapped pages compared to a specific language (that is: <math> \frac{EN\cap HE}{EN}</math>). This matrix is not symmetric.
