Checkerboard Pattern in APL

Introduction

APL (A Programming Language) is a high-level, multi-paradigm programming language that is widely used in various fields such as finance, data analysis, and scientific computing. One of the unique features of APL is its ability to perform complex operations in a concise and efficient manner. In this article, we will explore how to efficiently print a checkerboard pattern in APL, inspired by the Caveman (1978) style.

Checkerboard Pattern in APL

A checkerboard pattern is a grid of squares, alternating between two colors. In the Caveman (1978) style, the pattern is printed using a simple and elegant approach. We will use the APL dyadic function ckrboard to print the checkerboard pattern.

APL Code

The APL code for printing the checkerboard pattern is as follows:

ckrboard ← {⍺⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵⍵<br/>
