Java recursive Fibonacci sequence
... fibonacci(3) + fibonacci(2)
fibonacci(2) = fibonacci(1) + fibonacci(0)
Now you already know fibonacci(1)==1 and fibonacci(0) == 0. So, you can subsequently calculate the other values.
Now,
fibonacci(2) = 1+0 = 1
fibonacci(3) = 1+1 = 2
fibonacci(4) = 2+1 = 3
fibonacci(5) = 3+2 = 5
And from fi...

dict(zip(keys, values)) does require the one-time global lookup each for dict and zip, but it doesn't form any unnecessary intermediate data-structur...
