As I am getting my Linq query to a functional point, I start looking at the query and think about all the "ANY" and wonder if those should be a different method and then I have data conversions going on.
Does anything jump out as being a performance issue? What is recommended to make this more performant? (Yes, I need ... |
I am learning actionscript 3 coding by making a crappy platformer game :)
The problem I am facing is passing lots of options to a construct function that will setup the display object where all of them have default values.
I could send the options the normal way, like this:
function Box(param1:Number=1, param2:Number=... |

Here is the question followed by my working program:
Given a string, return a version without the first 2 chars. Except
keep the first char if it is 'a' and keep the second char if it is
'b'. The string may be any length. Harder than it looks.
deFront("Hello") → "llo"
deFront("java") → "va"

Does the code below respect Python programming conventions? (and if not, which one does it disrespect?) The objective would be to publish this code as part of a scientific article, as "reproducible research".

I was writing a function (named listenString) in haskell to see if a string contains one of the strings in a list of strings, and to then return a value (of the type m ()) that corresponded with the string it found. The type of that function is (Eq a, Monad m) => [a] -> [([a], m ())] -> m ().
