Introduction
We define twin primes as two natural numbers p,p+2 which both are prime.
Example: 5 and 7 are twin primes.
Let's define the twin number of some set of numbers as the number of twin prime numbers in that set
Example: {6,7,11,13,18,29,31} has a twin number 2, since there are two t...
Write a program or function that takes in a positive integer N and outputs the first N numbers of this amplifying zigzag pattern, using only the lines needed:

In computer programming, string interpolation (or variable interpolation, variable substitution, or variable expansion) is the process of evaluating a string literal containing one or more placeholders, yielding a result in which the placeholders are replaced with their corresponding values. It is a form of simple template processing or, in formal terms, a form of quasi-quotation (or logic substitution interpretation). String interpolation allows easier and more intuitive string formatting and content-specification compared with string concatenation.
String interpolation is common in many programming...

Chessmen (kings, queens, rooks, bishops, and knights) and pawns are on a board, but not on the a1 or h8 square. Your task is to travel from the empty a1 to the empty h8 squares, passing through only empty squares. The rules of movement are as follows:
