e58a5e6842 Update tim_sort.py (#972)
* Update tim_sort.py


Update tim_sort.py

The previous algorithm was skipping numbers, according to issue #959, and my own tests.
The version I am applying uses a while loop, which works correctly and is easier to compute, as there is no break statement.

46bc6738d7 Add doctest to maths/sieve_of_eratosthenes.py and remove other/finding_primes.py (#1078)
Both of the two files implemented sieve of eratosthenes.
However, there was a bug in other/finding_primes.py, and the time complexity was larger than the other.
Therefore, remove other/finding_primes.py and add doctest tomaths/sieve_of_eratosthenes.py.

9fcfe6a02b Commented doctests that were causing slowness at Travis. #2 (#1041)
* 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()'

* Added Burrows-Wheeler transform algorithm.

* Added changes suggested by cclauss

* Fixes for issue 'Fix the LGTM issues #1024'.

* Added doctest for different parameter types and negative values.

* Fixed doctest issue added at last commit.

* Commented doctest that were causing slowness at Travis.

* Added comment with the reason for some doctest commented.

* pytest --ignore

* Added tests execution again.

* Had forgotten to add comment to file project_euler/problem_09/sol3.py
