* Update mergesort.py
1) Updating the merge sort in python as the previous implementation was modifying the input array
2) divided the division part and conquer part of the merge sort algorithm as 2 functions namely mergeSort and merge.
3) function mergeSort divides the function into halves i.e the purpose of the function will be to divide the array
4) function merge will merge 2 halves into a sorted array
5)Added random test cases using shuffle as suggested by @dhruvmanila
6 The time and space complexity of the previous and my version remains the same. i.e (n log(n) time and n log(n) space
7) changed variables as per the python case as required and suggested by @dhruvmanila
8) Updated function names as suggested by @dhurvmanila
* Update mergesort.py
Added in few more test cases
added type hints for the functions and parameters as suggested by @dhruvmanila
formatted the code using Auto Pep8
* Update mergesort.py
update and added new testcases
* Update mergesort.py
Added in doc test in merge function
* Update mergesort.py

* Rename all Project Euler directories:
Reason:
The change was done to maintain consistency throughout the directory
and to keep all directories in sorted order.
Due to the above change, some config files had to be modified:
'problem_22` -> `problem_022`
* Update scripts to pad zeroes in PE directories
* Update README.md for Project Euler
* Add link to solution template
* Add newlines for better separation
* Add __name__ == __main__ block in template
* Apply suggestions from code review

* Trying to time every solution
* Proposal 2 for timing PE solutions:
- Use pytest fixture along with --capture=no flag to print out the
top DURATIONS slowest solution at the end of the test sessions.
- Remove the print part and try ... except ... block from the test
function.
* Proposal 3 for timing PE solutions:
Completely changed the way I was performing the tests. Instead of
parametrizing the problem numbers and expected output, I will
parametrize the solution file path.
Steps:
- Collect all the solution file paths
- Convert the paths into a Python module
- Call solution on the module
- Assert the answer with the expected results
For assertion, it was needed to convert the JSON list object to
Python dictionary object which required changing the JSON file itself.
* Add type hints for variables
* Fix whitespace in single_qubit_measure
* Removed print error_msgs at the end of test:
This was done only to reduce the message clutter produced by 60
failing tests. As that is fixed, we can produce the traceback in
short form and allow pytest to print the captured error message
output at the end of test.
* Start validate_solutions script for Travis CI
I am separating out the solution testing and doctest as validating
the solutions for the current number of solutions present is
taking 2 minutes to run.
