MDIzOTYzMGQ5ZGFlYzE3ZWI5OTI0OGFlYTAyYTViNDY0ZTZjZDBhZjc1MmNj In this program Fibonacci(n) = Fibonacci(n-1) + Fibonacci(n-2), that's why its recursive. Here, we will start the recursion from the forward direction and reach and hit the base condition at the end/last position. NTQ5Nzc1NWVjNzJiYzBhZDM3Mzg3NDMxYmQ1NmM4NTBjMDQ5N2ZjMWRlYmM1 Try to call the optimized version first and you'll get the inverse result.4) The program should produce a collection of fibonacci numbers. The following code has been written in three different ways, using standard values, using do while, recursion, command line arguments, creating a separate class, user-defined method. Example Live Demo #include <iostream> using namespace std; int sum(int n) { if(n == 0) return n; else return n + sum(n-1); } int main() { int n = 10; cout<<"Sum of first "<<n<<" natural numbers is "<<sum(n); return 0; } Output Sum of first 10 natural numbers is 55 No need to memorize, we'll see the approach below. The difference you see is only due to the fact that you are calling the "non optimized" version first. Print numbers without using loops. In other words, if the number is completely divisible by 2 then it is an even number. Then we shall go through a Java program that uses formula to find the sum.
