qualcosa di veramente inutile  
la serie di Fibonacci tradizionalmente inizia con (1,1); però… provate  
questo script

iccanobif = (1…10).inject(f = [1,1]) {|f, n| f.insert(-1,(f[-2] -  
f[-1])) }  
p “#{‘fibonacci’.reverse}([1,1],10) = #{iccanobif.inspect}”

fibonacci = (1…10).inject(f = [1,1]) {|f, n| f.insert(-1,(f[-2] +  
f[-1])) }  
p “fibonacci([1,1],10) = #{fibonacci.inspect}”  
seeds = [[1,1],[0,1],[1,0],[-1,1],[2,-1],[-3,2],[5,-3],[-8,5]]  
(0…(seeds.size)).each do |i|  
seed = seeds[i].dup  
n = 10 + i  
fib = (1…n).inject(seed) {|f, n| f.insert(-1,(f[-2] + f[-1]))}  
p “fib(#{seeds[i].inspect},#{n}) = #{fib.inspect}”  
end

scusate la divagazione, ma Ruby mi fa questo effetto
