Types

A type is a collection of possible values. An integer can have values 0, 1, 2, 3, etc.; a boolean can have values true and false. We can imagine any type we like: for example, a HighFive type that allows the values "hi" or 5, but nothing else. It's not a string and it's not an integer; it's its own, separate type.

Statically typed languages constrain variables' types: the programming language might know, for example, that x is an Integer. In that case, the programmer isn't allowed to say x = true; that would be an invalid program. The compiler will refuse to compile it, so we can't even run it.

Atbash is a simple substitution cipher possible with any known alphabet. It emerged around 500-600 BCE. It works by substituting the letters of an alphabet with another.

English alphabets in order is the constant.

CONSTANT = 'abcdefghijklmnopqrstuvwxyz'

A random shuffle of the constant is the ciper.
