I've seen on the site questions where too simple tasks can be grouped into one.
Here are Challenge 1 & 2 from Crypto Challenge Set 1 in Python.
Any suggestions?

I decided to create a double pendulum simulation to trace out its path and explore chaos theory a bit. I'm looking for any feedback regarding my code. Are there any atrocious portions of my code or bad practices I did?

I have been writing a math library with more options than the standard builtin one, partially to make my life easier in the future, and partially just for practice.
Here is what I have so far in the main file (master/xtrmth/xm.py):
import typing as tp
import decimal as dc
_meganum = tp.Union[in...
See following code snippet.
For me it looks too complicated, and it doesn't feel like it is the optimal solution for this problem. But to be honest I do not find any other solution. Mapping to other objects is to keep each layer input data separated. Further each object validates itself in the co...
this is a function given an array of numbers to find the one that appears an odd number of times.
what I did is:
Sort the array
Check if the array is odd.
If the array length is 1 then return this value.
Assign every two values to a new array, and check if it is a number.
Check if every two valu...
Is this a correct implementation of a generic Meyers Singleton in C++17? Any tips appreciated.

#define SINGLETON_H
template<class T>
class Singleton
{
public:
static T& get()
{
static T obj;
return obj;
}

I wanted to ask you a favor.
I am recruiting for the position of Junior Python Developer (my first try in IT) and I got a task to create a script to manage the task list.

Could you please give me some feedback about that script? I will be very grateful!
Thanks i...
Note: the optimal path can be chosen as the shortest path or the longest path
I made a randomized algorithm for finding random paths in a graph. The graph has weights on the edges. For non-cyclic graphs, the algorithm does not form any cycles. However, cyclic graphs can form cycles.
These paths ...
I wrote a program about triangular numbers, which are derived from the sum of natural numbers one after the other. For example, the third triangular number is equal to: 1 + 2 + 3 = 6. NOW I WANT to find Divisors of triangular numbers. for example the third triangular number have 4 divisors which ...

This class is intended to fulfill these requirements:
Output in Y-m-d H:i:s format
Allow dates to be entered as m-d-Y or m-d-y
Complain if an invalid birthdate is entered (i.e., in the future or otherwise)
Allow simpler, friendlier coding without typing a lengthy DateTime instantiation
