I write a program. Most of the time it work out really fine. But occasionally it would crash due to segfault. So I wonder whether it is proper to post such a snippet of code.
Most program contain bug. Some are big while others are small. Mine contain a little bug that I cannot find out. I need ...
Bugs can be big, bugs can be small, it is still a bug. Unfortunately, this is off-topic.
Many numbers can be expressed as the sum of a square and a cube. Some of them in more than one way.
Consider the palindromic numbers that can be expressed as the sum of a
square and a cube, both greater than 1, in exactly 4 different ways.
For example, 5229225 is a palindromic number ...

I made a chat bot, that, as you talk to it, it learns to respond. But the way it speaks is strange, so if you have any ideas on how to make its response any more human, then please say so.
Anyway, you have to start a new chat bot. You'll notice that when you start his responses will be incredibl...
Whitespace. It looks nice, and is important. Use it. There are many areas here where you could insert some whitespace, and then the code will magically become much easier to read. Here are a few areas where whitespace is needed.

What is the best algorithm to solve for this problem?
You are given a bunch of nodes evenly spaced in a rectangular shape. The rectangle is M nodes long and N nodes wide. Node A is in the upper left hand corner and node B is at the bottom right hand corner. How many different paths are there fro...

Problem Statement
There are N boys and N girls. Only a boy and a girl can form a dancing
pair (i.e. no same sex dancing pairs are allowed). The only other
condition in making pairs is that their absolute difference in height
should be less than or equal to K.

I would like to create a plugin system to allow new controllers to be added at runtime. These will be api controllers and not views.
I know I can add controllers from other assemblies at startup by using the following and this works.

For practicing purposes, I challenged myself to write a program that solves the TSP and visualises the results step by step.
As for now, my program uses a simple nearest neighbour algorithm. I want my program to be flexible, so when I add a new algorithm, it will be able to visualise the result...
The Problem
Given a list of dependencies ('a * 'a) list where the first item has a dependency on the second item, construct a dependency graph and then 'flatten' it into a single 'a list such that no item comes after one of its dependencies.

I am writing a fully tested program to solve the following problem:
A triangle needs a good foundation. Every row in the triangle is derived from the sum of the two values below it. However, there can be

I've written a little program to calculate pi using the Nilakantha series
For this formula, take three and start alternating between adding and subtracting fractions with numerators of 4 and denominators that are the product of three consecutive integers which increase with every new iteratio...

My Rails app geocodes users IP when they are created and also when they update their data only if they change their city. The geocoding is slowing down my tests ridiculously.
This seems to me to be a poor way to avoid endless geocoding when running tests but i am unsure of a better way to do th...

Every time a post involves Python code, it has the Python tag AND the Python version tag that suits the version of Python that the post is using.
I think that is a little repetitive, and we should either:
Burn python and have Python related posts use the tag that contains the version of Python...

I want this code to run, get to the end, print the value of pi for that run, and then do it again- 40 times, without me hitting the run button again. In other words, I want to see 40 different estimations of pi in the "run" window. As you can tell I'm new to programming, I've read about for an...
