c8db6a208b Add solution for Project Euler problem 123 (#3072)
Name: Prime square remainders

Let pn be the nth prime: 2, 3, 5, 7, 11, ..., and
let r be the remainder when (pn−1)^n + (pn+1)^n is divided by pn^2.

For example, when n = 3, p3 = 5, and 43 + 63 = 280 ≡ 5 mod 25.
The least value of n for which the remainder first exceeds 10^9 is 7037.

Find the least value of n for which the remainder first exceeds 10^10.

44254cf112 Rename Project Euler directories and other dependent changes (#3300)
* 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`

29b32d3553 Improve validate solutions script & fix pre-commit error (#3253)
* 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

69f9283825 Start running validate_solutions script for Travis CI (#3215)
* 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.

2b5b2c6304 Added solution for Project Euler problem 119 (#2931)
Name: Digit power sum

Problem Statement: The number 512 is interesting because it is equal to the sum of its digits raised to some power: 5 + 1 + 2 = 8, and 83 = 512. Another example of a number with this property is 614656 = 284.
We shall define an to be the nth term of this sequence and insist that a number must contain at least two digits to have a sum.
You are given that a2 = 512 and a10 = 614656.
Find a30
