var x=0, var y=1; var z; fib[0] = 0; fib[1] = 1; for(i=2; i<=10; i++) { alert(x+y); fib[i]=x+y; x=y; z=y; } I'm trying to get to generate a simple Fibonacci sequence but there no output. Can anybody let me know what's...

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;...

function fibo() { var first,second,add; for(var i=0;i<4000;i++){ if(i === 0){ first = 1; second = 2; } add = first + second; first = second; second = add; } alert(add); } fibo(); not working shows infinity...

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've seen several posts on generating a given fibonacci sequence, such as this one. However, I can't figure out how to generate the sequence (return an array) of fibonnaci numbers for a given n using recursion. What I have clearly doesn'...

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 need to create a web server with rest service in node.js. The server have to find a given input is Fibonacci or not. If it is Fibonacci, find the next number in Fibonacci sequence. So I just write a simple program for finding Fibonacci number, but...
