At the Code-Golf™ Psychological Society, you are delighted to present a new method of measuring mental age: Abstract Capacity™.
To get the Abstract Capacity of a person, you take their actual age divided by 4, take their IQ divided by 9, then add the two values together. Then, round this sum dow...
Is this a valid Takuzu board? code-golf decision-problem
Takuzu is a logic game in which you have to complete a grid with 0s and 1s. The grid must follow 3 rules:
No three horizontal or vertical grids in a row can be the same.
There must be an equal number of 0s and 1s in each row and column.

Given a non-empty array of integers x and a positive integer n, compute the sum of each sliding block of length n along the array x, circularly filling the missing values at the left with values from the right as follows:
the first block contains the f...

Help Me Catch Up With xkcd! code-golfinternet
I definitely enjoy xkcd, and you, as a code golfer, most likely enjoy it as well. However, I often find that I won't check the website for a while and there will be a lot to read! So, I want to make a solution for that. In proper code golf fashion.

Who are they?
Primus-Orderus Primes (POP) are primes which contain their order in the sequence of primes.
So the nth prime, in order to be POP, must contain all the digits of n in a certain way which I'll explain.
Examples
Let's get things clearer:
All digits of n must appear among the digits...
Earlier I defined the process of crushing an array
In a crush we read the array left to right. If at a point we encounter two of the same element in a row we remove the first one and double the second one.
Now crushing arrays is easy, whats hard is uncrushing them. Your task is to take an...
Yes it is, at least for some flags. You can push and pop diagnostic settings like this:
#pragma GCC diagnostic error "-pedantic"
#pragma GCC diagnostic warning "-Wall"
This is also possible for optimization levels on a per-function level:
#pragma GCC optimize ("string"...)
See these other q...

Given an array of positive integers, output a stable array of the unique prime factors of these integers. In other words, for each integer in the input, add all prime factors of that integer not already in the output array to the output ar...
