I saw this Puzzling problem and thought I would try to write a python program to solve it. But turns out I don't know how to optimize recursion, so I'm posting here for help. I'm mostly just confused on why the code to change the past needs to be at the top of the function, but I would also like ...
I have a use-case where I need to retrieve all members with specific attributes in the class and interface hierarchy - I usually need the first match and apply its rules to child members. The built-in GetCustomAttributes are too limited becuase they work only for a single member and don't support...
Consider the following code:
// variant 1
if (clearPattern)
{
clearPattern = false;
}
// variant 2
if (numericValue != newValue)
{
numericValue = newValue;
}
Are the conditional checks in this case really necessary?
I mean if condition is satisfied, assignment will happen.
If not sati...

I have a vba code which checks all the pivots in specified worksheets to add a range of pivotfield to the values/data section of the pivot because the pivot headers change every 4 weeks.

The dataframe subset feature is being used in a for loop across the dataframe rows. The result seems accurate however, the time taken to complete the loop on 2000 odd rows is more than 4 minutes. Any advice or guidance on the quality of the code?

I'm toggling the class of an element with this code but I'm pretty sure it can be written more efficiently.

I would like to change row names values from a first data frame if these rows names are present in another data frame, and change it to a corresponding value (defined in the second data frame). I could do it with a for loop, but I wonder what would be some other more suitable ways to do it in R. ...

I can do this in one line in Python:

Not very fast, but works nicely. I thought it might be quicker to do in Haskell, a language I'm quite new to:

Well, whatever it is, it is certainly not a duplicate. The follow-up question asks about the proper use of divs and spans; the original question contains no spans.
I agree that it is rude to ask a follow-up question without adding mutual links, because that wastes other users' time. However, t...
This QA site doesn't quite take the form that others do. Here, we have fairly specific questions. But I already see two Project Euler #1 questions that are similar. Are these duplicates?

When I was looking to use std::bitset instead of GCC's __uint128 in my RDS error-corrector, I found that it was hard to use, because there's no way to widen or truncate a bitset to one of another size. Nor is there any ability to do bitwise arithmetic (&, |, ^) or comparison (==, !=) with a bits...
I'm a few weeks into javascript and had to make a simple "crystals collector" app. The app works as intended, but the code is obtuse and repetitive.
I'd like to make the app work using just one on click event, rather than using four for each crystal. I can't make an array of each color crystal a...
I see rop was recently added, to refer to "Railway-oriented programming" (which I have to admit was new to me, not having come across the term when I was using functional Scheme).
However, the initials ROP have other uses, notably "Return-oriented programming", so perhaps this name isn't the bes...
