Posted 2021-05-14

class FibonacciSequence
  def call(number)
    number < 2 ? 1 : call(number - 1) + call(number - 2)
  end
end

#include <iostream>

int fibonacci_sequence(int number);

int main(void) {
  return 0;  
}

int fibonacci_sequence(int number) {
  return number < 2 ? 1 : fibonacci_sequence(number - 1) + fibonacci_sequence(number - 2);
}
