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...
