I have made a website where people write about their day and see it analyzed. In particular, the website takes event titles and groups them together if they have any common words (after stemming the event titles). The class that is most important is EventAnalysis, and its most important methods a...

All inputs will be in lowercase.
The order of your output does not...
I was reading CLRS and I was stuck at question 5.1-2.
Describe an implementation of the procedure RANDOM(a,b) that only makes calls to RANDOM(0,1).What is the expected running time of your procedure, as a function of a and b?
The solution written here provides a complexity of O(lg(b-a)).

I would like to collect feedback on possible solutions for creating testable classes/interfaces.
In a normal non-embedded C++ development we can use references/pointers and forward declarations to achieve dynamic polymorphism (see "Solution with references" below).
However with the embedded con...
I am using the dynamically allocated string named *buffer to store the contents of the string time_digital, in order to tokenize the string using __strtok_r() function defined in #include<string.h>.
I have written the following logic to tokenize the string time_digital which contains the time i...
Basically, I'm lazy.
And so, since I don't want to write multiple times the same table HTML, I've made a very ... convoluted macro.

{% set default = {
'width': '100%'
} %}
{% set options = default|merge(options) %}

I am a newbie in the scientific computing in python. The function I am trying to calculate is the response of the wave equation for a given source term (For reference, See: Equation 11.67 in https://webhome.phy.duke.edu/~rgb/Class/phy319/phy319/node75.html).
To give context, the term phi in the...

There aren't enough questions about creating immutable objects... so why not try it again with another approach. This time, it's a builder that maps properties to constructor parameters. Properties are selected via the With method that also expects a new value for the parameter. Constructor param...
For a =2, the answer is 10. But my question in unary operator is higher precedence than arithmetic operators. So why doesn't it be 12?
int i = 2,b;
b = i + ++i + ++i;
printf("%d\n", b);
I have to transform a response into the internal Coordinate record, some of the fields are lists and I need to handle empty lists case.

The input is a set of alphabets.
The output is a string of 32 in length.
For any letter in the set if it is preceded by a '¬' we replace the n-th character in our output string with '0', such that n is the position of the letter in the alphabets. If it is not preceded by a '¬' and was there in ...
I've created a static method in Swift that acts as a factory method for creating MyViewController instances.

I have written a Regex to validate XML/HTML, along with any attributes. It aims to:
Match any XML-like text
Not match any unclosed tags
Adapt for any spacing, newlines, etc.
Be as generous as possible: match as much as possible.
I initially created this to validate API requests I was making, ...
I got caught in the trap of implementing my own data structure. I'm mostly looking for advice on how to make this code more idiomatic, but also functionality that might be missing from this class, or that isn't necessary. I would also like thoughts on how idiomatic the traverse function is, and i...
I am a member of a university team designing a nanosatellite.
We decided to implement our own (more lite) logging library to use, instead of, say, Google's glog, spdlog, plog and Boost::Log.
The concept of different log levels is introduced, as a means of dividing the log messages into subcateg...
