Excel, ??? bytes =CHAR(64+MAX(COLUMN(A1),ROW(A1))) The forumula is 33 bytes, but you need to copy it 26^2 times (and cell references grow larger). Paste this formula in A1, then drag all over A1:Z26.

Mathematica, 69 bytes StringRiffle[ToUpperCase@Alphabet[][[Max@##]]&~Array~{26,26}," ",""]& Anonymous function. Takes no input and returns a string as output. Basically just takes letters[max(x, y)] for all x, y from 1 to 26.

Sending values into generator functions. For example having this function: def mygen(): """Yield 5 until something else is passed back via send()""" a = 5 while True: f = (yield a) #yield a and possibly get f in return if f is not None: a = f #store the ...

I've been trying to learn how CPython is implemented under the scenes. It's great that Python is high level, but I don't like treating it like a black box. With that in mind, how are tuples implemented? I've had a look at the source (tupleobject.c), but it's going over my head. I see that PyT...

Graham's number G is defined in this way: u(3,n,1) = 3^n u(3,1,m) = 3 u(3,n,m) = u(3,u(3,n-1,m),m-1) [Knuth's up-arrow notation] [Conway chained arrow notation] THEN g1 = u(3,3,4) g2 = u(3,3,g1) g3 = u(3,3,g2) ... G = u(3,3,g63) You are given that u(3,3,2)=7625597484987 to check your code. ...

Jelly, 6 bytes ṗ’S€ċ⁵ This is a full program that accepts m, n and the exponent as separate command line arguments. Try it online! How it works The problem boils down to counting the number of ways we can express the exponent as an ordered sum of exactly n integers between 0 and m - 1 (both...

Vim, 11 keystrokes C<C-r>=<C-r>"<C-Left>%<C-Right><1<cr> Not bad for a language that only handles strings. :D

I was messing with the expression register (:h @=) and noticed that it is not possible to put text directly in it. The doc says: The expression register is read-only; you cannot put text into it. Let's say my buffer contains an operation like that: 1+2+3+4 If I want to get the result in ...

Is it possible to call a class instance in C#? For example, is it possible to do this? MyClass myClass = new MyClass(); myClass();

I would like to use (pure) regex to match strings that do not contain the word word. However, I would not like to use lookaround, balancing groups, or that kind of stuff. If it is impossible, then can we match strings that do not start with word instead? Examples word should not match. wor...

I am currently developing a simple C application. It takes a single file as a command line argument, which is formatted like: 1,2,3 4,5,6 7,8,9 etc. However, for whatever reason, fscanf never scans the numbers! Here is an example: #include <stdio.h> int main(int argc, char **argv) { FILE...

K, 0 bytes Or maybe 2 bytes. Or 18 bytes. Or 20 bytes, depending on what you're actually counting. Let me explain. In K, function application uses the same syntax as indexing, so 0000b is a valid "function", and the function 0000b can be applied directly if p and q are in the right format (and...
