On puzzling SE there are what are called "matchstick problems" in which math is written in match sticks and you are allowed to move a certain number of them to get a certain property.
In this question we will be considering only integers represented in a 7-segment display format. Here are all 1...
When an error is the correct output
The task
You should submit two full programs or functions which produce the same (non-empty) result, but the first one should produce it as an error while the second one should produce it as a standard result.
Rules
The two functions/programs will receive ...

I'm hoping we're nearing the end of beta soon, but even if we aren't, our chatroom name is so bland. "Code Golf." Look at all the creative names others have thought up:
"Root Access" for Super User
"The DMZ" for Security
"The Renderfarm" for Blender
"The Litter Box" for Pets
"The Hangar" for Av...

How Fermat is this number? code-golf
Fermat numbers are positive integers that can be expressed as 22x+1 with an integer x.
Let us now define an attribute of a number called "Fermat-ness":
The Fermat-ness of the number is one less than the amount of consecutive twos in the power tower compone...
Problem
We wish to visualize Euclid's algorithm for computing the greatest common divisor of two numbers as a 2-dimensional tiling, such as this one:
This interactive version may also be helpful in understanding the visualization.
Input
Two positive integers a and b, where a > b. You may t...

Challenge
Given a strictly positive strictly ascending integer list L and an integer 3 ≤ N ≤ length of L, replace the middle integers of L's consecutive integer runs of length ≥ N with a single dash -.

In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it represents. For example, the expected value in rolling a six-sided die is 3.5, because the average of all the numbers that come up in an extremely large number of rolls is close to 3.5. Less roughly, the law of large numbers states that the arithmetic mean of the values almost surely converges to the expected value as the number of repetitions approaches infinity. The expected value is also known as the expectation, mathematical expectation, EV, average...
