* Added doctest and more explanation about Dijkstra execution. * tests were not passing with python2 due to missing __init__.py file at number_theory folder * Removed the dot at the beginning of the imported modules names because 'python3 -m doctest -v data_structures/hashing/*.py' and 'python3 -m doctest -v data_structures/stacks/*.py' were failing not finding hash_table.py and stack.py modules. * Moved global code to main scope and added doctest for project euler problems 1 to 14. * Added test case for negative input. * Changed N variable to do not use end of line scape because in case there is a space after it the script will break making it much more error prone. * Added problems description and doctests to the ones that were missing. Limited line length to 79 and executed python black over all scripts. * Changed the way files are loaded to support pytest call. * Added __init__.py to problems to make them modules and allow pytest execution. * Added project_euler folder to test units execution * Changed 'os.path.split(os.path.realpath(__file__))' to 'os.path.dirname()'

Name scores
|
||
Problem 22
|
||
|
||
Using names.txt (right click and 'Save Link/Target As...'), a 46K text file
|
||
containing over five-thousand first names, begin by sorting it into
|
||
alphabetical order. Then working out the alphabetical value for each name,
|
||
multiply this value by its alphabetical position in the list to obtain a name
|
||
score.
|
||
|
||
For example, when the list is sorted into alphabetical order, COLIN, which is
|
||
worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list. So, COLIN would
|
||
obtain a score of 938 × 53 = 49714.
|
||
|
||
What is the total of all the name scores in the file?
