Excel: last character/string match in a string
...gh it's replicable in older versions (yet I have not seen it before), when one has Excel O365 one can use:
=MATCH(2,1/(MID(A1,SEQUENCE(LEN(A1)),1)="Y"))
This can also be used to retrieve the last position of (overlapping) substrings:
=MATCH(2,1/(MID(A1,SEQUENCE(LEN(A1)),2)="YY"))

How can I get list of values from dict?
...
There should be one ‒ and preferably only one ‒ obvious way to do it.
Therefore list(dictionary.values()) is the one way.
Yet, considering Python3, what is quicker?
[*L] vs. [].extend(L) vs. list(L)

What is the difference between atomic / volatile / synchronized?
..., then the first assigns a new value to i (say, from 1 to 6) and the other one does the same thing (from 1 to 6).

Where can I learn how to write C code to speed up slow R functions? [closed]
...d Use the source, Luke! --- R itself has plenty of (very efficient) C code one can study, and CRAN has hundreds of packages, some from authors you trust. That provides real, tested examples to study and adapt.
But as Josh suspected, I lean more towards C++ and hence Rcpp. It also has plenty of exa...

Finding the mode of a list

Can anyone explain how this works for bi-modal distributions? e.g. a = [22, 33, 11, 22, 11]; print(max(set(a), key=a.count)) returns 11. Will it always return the minimum mode? And if so, why?
