A few moments thought reveals that the sequence must begin as follows: n 1 2 3 4 5 6 7 8 9 10 11 12 f n 1 2 2 3 3 4 4 4 5 5 5 6 In this problem you are expected to write a program that calculates the value of f n given the value of n. Sample Input 0 Sample Output 21 Programming Explanation This is very simple problem states that for given range of n as input as shown in above image , we have.
How many fibs? Which can be stated as from online judge. Given two numbers a and b, calculate how many Fibonacci numbers are in the range [a,b]. That's it, our jobs is to calculate total number of fibonacci numbers in given range. This problem is pretty straight forward and doesn't need any explanation. Here, assuming that user range will consist first fibonacci numbers thus we first calculate fibonacci series upto as series length, and store it in 'fibbo' list.
Then we simple check how many numbers belongs to given range and display count.

Given two numbers a and b , calculate how many Fibonacci numbers are in the range [ a , b ]. The input contains several test cases. Each test case consists of two non-negative integer numbers a and b. Otherwise, a b 10 The numbers a and b are given with no superfluous leading zeros.
For each test case output on a single line the number of Fibonacci numbers f i with a f i b. This is one of those problems where overthinking slows you down.
There are no tricks here. You need to be able to add BigIntegers to create fibbonaci numbers as needed. I implemented a quick BigInteger struct and implemented addition for it and that was it.
