Generate Negafibonacci Numbers

Negafibonacci Number Generator

Introduction: Welcome to the Negafibonacci Number Generator! This tool enables you to generate Negafibonacci numbers up to a specified limit. Negafibonacci numbers are a variant of the Fibonacci sequence where each number is the difference of the two preceding ones. This sequence finds applications in diverse areas such as combinatorics and theoretical computer science. With this tool, you can explore the Negafibonacci sequence and its properties effortlessly.

Steps to Use the Tool:

  1. Enter the desired limit for generating Negafibonacci numbers.
  2. Click the "Generate Negafibonacci Numbers" button.
  3. View the generated Negafibonacci numbers in the output area.

Functionality: The Negafibonacci Number Generator utilizes a JavaScript algorithm to calculate Negafibonacci numbers efficiently. It starts with the base Negafibonacci sequence [0, 1] and iteratively generates subsequent Negafibonacci numbers until reaching the specified limit. The generated numbers are then displayed for further analysis or application.
