Challenge
Given some input string, return a truthy value if it represents a correct roman numeral between 1 (=I) and 3999 (=MMMCMXCIX), and a falsey value otherwise.

The input is a non-empty string that only comprises the characters IVXLCDM.
The roman numerals (that we use here in thi...

A Megachess board looks like a normal chess board but can be of different sizes. The board should be square, and the neighboring cells should be of different colours. The cell in the lower left corner can be either black or white.

Unfortunately I screwed myself over. I can think of two ways to do it in vim. The first fails with spaces in the output, and the second way fails with multiple characters on one row.
Otherwise, Vim, 16 bytes is a really cool solution: :sor!|%s/\_s//g<cr>
@Adám untested, but I believe it works, it basically splits the input by newlines and then takes the maximum of each column (won't work for control chars)
note that if a column is all-spaces the maximum is a space, not nothing
@EriktheOutgolfer Accessing data in PowerShell via matrix indexing (e.g., $a[5][4]) is quite messy and prone to unexpected behavior. Plus there's no transpose or other matrix manipulation.

Given a string as input (ASCII printable characters only), output the string with the letters "raining" down. Each letter must be a random number of spaces downward (random between 0 and the length of the string, eac...

Recognizing primality seems like a poor fit for (artificial) neural networks. However, the universal approximation theorem states that neural networks can approximate any continuous function, so in particular it should be possible to represent any finitely-supported function one desi...
