Java recursive Fibonacci sequence
...ci(n - 2)
is very wrong.
The problem is that the it calls fibonacci not 50 times but much more.
At first it calls fibonacci(49)+fibonacci(48),
next fibonacci(48)+fibonacci(47) and fibonacci(47)+fibonacci(46)
Each time it became fibonacci(n) worse, so the complexity is exponential.
The approach to...

I use pandas.to_datetime to parse the dates in my data. Pandas by default represents the dates with datetime64[ns] even though the dates are all daily only.
I wonder whether there is an elegant/clever way to convert the dates to datetime.date or datetime64[D] so that, when I write the data t...
Python : List of dict, if exists increment a dict value, if not append a new dict
...class int; when Python calls int() it returns a zero value. So, the first time you reference a URL, its count is initialized to zero, and then you add one to the count.
But a dictionary full of counts is also a common pattern, so Python provides a ready-to-use class: containers.Counter You just c...
