## Fibonacci sequence – How to calculate the sum of the first 100 even-values Fibonacci numbers?

Fibonacci sequence is defined as a sequence of integers starting with 1 and 1, where each subsequent value is the sum of the preceding two I.e. My goal is to calculate the sum of the first 100 even-values Fibonacci numbers. So far I’ve found this code which works perfectly to calculate the sum of even numbers to 4million , however

## Fibonacci Memoized/Dynamic Programming in Java

So this is some code to calculate the Fibonacci sequence with memoization. What confuses me is when we check if memo[i]==0. I understand that Java arrays are initialized to zero and thus if memo[i] == 0 this may mean that the computation for memo[i] has not yet occured. However, one of the return values for this fibonacci function is 0.

## Java how to return an array with fibonacci values starting at 1?

I’m writing a void function fibFill which fills an array with Fibonacci numbers. It doesn’t have to return anything. Here’s what I have so far: For example, if I pass an array of length 5 to the method, it will override the contents of the passed array like this: [1, 1, 2, 3, 5] Answer Your fibFill method shouldn’t have

## Fibonacci calculator with BigIntegers

I’m working on a homework project where I must have the user input a number, and the computer spits out the Fibonacci numbers up to that one. I’d normally be able to do this, with int values, except that for this program, I need to use the BigInteger type instead, because int, long, double, etc. types are too small to

## Java recursive Fibonacci sequence

Please explain this simple code: I’m confused with the last line especially because if n = 5 for example, then fibonacci(4) + fibonacci(3) would be called and so on but I don’t understand how this algorithm calculates the value at index 5 by this method. Please explain with a lot of detail! Answer In fibonacci sequence each item is the
