QUESTION
I've completed speller and passed all checks. But I'm still bugged about the performance. I did my best with research and running tests, but my implementation is slower by 10-20% compared to staff's one. How can I improve my code?
...ANSWER
Answered 2022-Mar-03 at 00:26A few issues:
while (fscanf(dict, "%s", word) != EOF)
is wrong. You want:while (fscanf(dict, "%s", word) == 1)
- Faster to store the given word into the table as uppercase. (i.e.) We do
toupper
only once for each word. - The
check
function will be faster because it can [then] usestrcmp
instead ofstrcasecmp
[which is slower] - If we can add fields to the
node
struct, we can have it hold a hash value. This can speed up thecheck
function (seeNODEHASH
in code below). - Doing a
malloc
for each node is slow/wasteful. A pooled/arena/slab allocator can be faster (seeFASTALLOC
in code below). Again, if we can add a field to thenode
struct.
There are some other bugs that are documented in the code below (see the "NOTE" comments). I've used cpp
conditionals to denote old vs. new code:
QUESTION
I will try and keep this as concise and easy to understand as possible. I have a dataset which includes a large number of names, some are distinct, however some are not and all names have a corresponding reference number. Where the names are not distinct, I want to create a query that will display a distinct list all of names in that table, and have seperate columns that list listing the reference numbers of the names in the original dataset. Is this at all possible using SQL? I was thinking a PIVOT clause might be required, but not sure that would be appropriate
Like below;
Current Dataset
FullName Reference Joe Bloggs T1234567 Joe Bloggs T3456789 John Smith T1234568 Sarah Edwards T1234567 Karen Culford T0999221 Sarah Edwards T0239222 Joe Bloggs T2045292Desired Outcome

Answered 2022-Feb-28 at 14:10If the number of pivot columns is unknown, you'd need dynamic sql (which has both pros and cons). Using this example as a base, first build a comma separated list of column names "Reference1,Reference2,....".

QUESTION
I have loaded some JSON API data as a Pandas dataframe, as such, there are some columns that come out as lists. I also have some NaN
values.
First and foremost I want to replace the NaN with a single word such as 'empty' but the rest of the data are already in list forms. I want to ultimately create a new column that operates on this list
structure and essentially turns it into a string since I will be using the strings to perform mapping logic later on.
Here is some sample data and logic:

Answered 2022-Jan-06 at 19:58IIUC, you can get all the rows with NaN
