I need to calculate the index of a Fibonacci number with JavaScript, within the Fibonacci sequence. I need to do this without using recursion, or a loop. I found the following formula in the Math forum: n=?log?(F?5?+12)? and coded it in JavaScr...

I have the memoization fibonacci code and I am having trouble figuring out what the time complexity is of it: function fibMemo(index, cache) { cache = cache || []; if (cache[index]) return cache[index]; else { if (index < 3) return 1;...

Trying to get my fibonacci sequence to work using recursion but am running into the error maximum callstack exceeded. Code: var genFib = function(count, limit, fibArray) { if (count === undefined || count === null) { var count = 0; } if...

I am trying to successfully complete this challenge on the Rosalind page. The challenge is: Given: Positive integers n?40 and k?5. Return: The total number of rabbit pairs that will be present after n months if we begin with 1 pair and in ea...

Yet Another (Project Euler) Fibonacci Question: Using (vanilla) javascript, I'm trying to sum the even numbers <= a given limit: First, something is wrong with my 'if' statement, as some of the results (below) are wrong: function fib...

I m trying to solve https://www.spoj.com/problems/FIBOSUM/ problem. MOD = 1000000007; function copy(a, b) { a[0][0] = b[0][0]; a[0][1] = b[0][1]; a[1][0] = b[1][0]; a[1][1] = b[1][1]; } function multiply(fib, base) { let mat =...

I was attempting to do some problems on project euler. For the second one I did get the correct answer but I cheated a bit. Heres the problem: Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting...

I am trying to find the first number in the Fibonacci sequence to contain over 1000 digits. Given a number n (e.g. 4), I found a way to find what place the first number with n-digits has in the Fibonacci sequence as well as a way to find the number...

<!DOCTYPE html> <html> <head> <title>Ambiente Web</title> <script type="text/javascript"> function fibo(num) { var f = []; for (var c = 0; c < num; c++) { f.push((c <...

I wrote a script with the purpose of sequencing the Fibonacci Sequence (or any two numbers that would add to make the next, and then those two, etc.). When you press a button, the function (called fibonacci) adds the two values together, pushes the n...
