minFibnn

minFibnn is a mathematical function that returns the minimum Fibonacci number greater than or equal to a given input value. The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones, usually starting with 0 and 1. The sequence begins as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, and so on.

The function minFibnn is particularly useful in various computational and mathematical contexts where Fibonacci numbers are involved. It can be implemented using an iterative approach to efficiently find the desired Fibonacci number without generating the entire sequence up to the input value.

The algorithm for minFibnn typically involves initializing the first two Fibonacci numbers and then iterating through the sequence until a Fibonacci number greater than or equal to the input value is found. This method ensures that the function runs in linear time relative to the size of the input, making it efficient for large values.

In summary, minFibnn is a straightforward yet powerful function that leverages the properties of the Fibonacci sequence to provide a minimum Fibonacci number based on a given input. Its implementation is straightforward and efficient, making it a valuable tool in both theoretical and practical applications.
