ask the teacher how many classes they wish to enter and run the program through all the classes. (Run this program for 3 classes.) In the end, after you have printed the 3 class averages, print the highest and lowest class average. The trick here is to figure out how to track which average is ...
Below is the etymology, from Jeff Miller's Earliest Known Uses of Some of the Words of Mathematics (F). Perhaps a native French speaker can lend further insight.
FACTORIAL. The earlier term faculty was introduced around 1798 by Christian Kramp (1760-1826).
Factorial was coined (in French...
This code works and does exactly what I want it to, but I feel that it is inelegant. It seems like there should be a way to use get() and/or setdefault(), for example. All comments and suggestions are appreciated!

My goal here is pretty simple, I want to turn a number like 12435987234 into an array of integers of reverse order. So that would look like:
[4,3,2,7,8,9,5,3,4,2,1]
I want to do this without changing the number to a string and back. Really, I don't want to convert it at all but I'm open to h...
On Code Review, "code dump" answers are not allowed. When an answer contains just code, moderators will often put the following warning notice on it:
We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right,...
Is the intent of this code obvious / clear? Please suggest any improvements. This happens to be TypeScript, but is probably pretty familiar to anyone in the Java/C# world.

I've been doing the Project Euler problems, but gotten stuck on number ten. Nothing I try seems to work, so I assume it's some trivial error I just haven't noticed.
The problem:
The sum of the primes below 10 is 2 + 3 + 5 + 7 = 17.
Find the sum of all the primes below two million.

A twinoid is defined to be an array that has exactly two even values that are adjacent to one another. For example {3, 3, 2, 6, 7} is a twinoid array because it has exactly two even values (2 and 6) and they are adjacent to one another. The following arrays are not twinoid arrays.
{3, 3, 2, 6, ...
As the title says, my program simply accepts the name of a directory from the user, scans said directory and generates an HTML file that lists the contents:
/*
Basically, take the path of a directory, get a list of all files in the directory
and output that list to an html document
*/

The compiler is smart enough to reuse variable slots for variables whose scopes do not overlap. Because they can never both be used at the same time, there is no need to store them separately.
Since hello and var6 have no overlap, the slot can be reused.
So here is the example:
LocalVariableTable:
Start Length Slot Name Signature
0 133 0 this Lcom/my/class/Test;
2 131 1 a I
4 129 2 b I
7 126 3 i I

In my Rails app, I have two classes each with the same enum for status. Code climate is complaining about duplication.
class Enrolment < ActiveRecord::Base

has_many :presentations, through: :enrolment_presentations
enum status: {
'Pending' => 1,

Forgive my ignorance, but isn't ActiveRecord::Base#enum just a method? Therefore, to help reduce duplication (but not eliminate it), you could do something like this:
STATUS_FLAGS = {
'Pending' => 1,
'Suspended' => 2,
'Cancelled' => 3,
'Pass' => 4,
'Fail' => 5,
'DPR' => 6,
'Unknown' =

Some of my tests require that I need to test the date time results (like time stamps etc.). In order to be able to test the date time string I created a simple DateTime abstraction that I'm going to use in other projects later. It should replace direct calls to DateTime.(Utc)Now.

This class is extension of this. Now I have added support to serialize array of TLV objects to byte array and vice versa. I posted also someone may find it useful in future (together with other TLVObject class).
