Code Golf.
Couldn't find one on the Google on the ATs so I decided to make one (please tell me if it's a dupe)
The idea is simple, someone say a program / algorithm to golf, and everyone will try and golf it!
Some starters:
FizzBuzz
Palindrome
Anagram
Some I've done (Python):
FizzBuzz:
Palindrome:
Use any language you wish.

One small question: Did my topic inspire you to make this topic?
2+2=4
2*2=4
2^2=4
2^^2=4
2^^^2=4

I take issue with all characters when I'm golfing. I despise the ‘k’ character, for example, because it takes up a whole byte. Yet I still golf in such languages, because all languages are made up of characters, which all take up entire bytes, and I lack a choice. I, personally, don't find the white-space character special in this regard.but whitespace is still requiredI like the challenge of removing as much whitespace as possible by changing the code in different ways never golf in a language that requires whitespace
If you just want short outputs, you might wish to use languages specifically designed for code golf. But generally, people compare code golf between identical languages, so that it's fair if you're using ‘normal’ languages – and so length shouldn't be a concern, therefore, when selecting your language.
If you find it difficult to detect the white space character visually, use a font where it doesn't look like empty space.
The byte associated with 32 doesn't have to map to a whitespace character in your encoding system either (this is quite similar to changing your font). However, note that choosing to never use the 32-nd byte means that you're able to write less programs in the same number of characters; which is bad for golfing

Then why do you think we shouldn't use languages that require whitespace?

This is my signature. It appears below all my posts. Discuss it on my profile, not the forums. Here's how to make your own.

You can save another 38 characters by more questionable means:
from random import*
i=g=0
a=randint(1,5)
while i-a:i=int(input());g+=1;print(((a>i)-(a<i))or g)

(NOTE: When putting code in replace the quotes “” with the standard python quotes or it will give an error from the different unicode upload used in scratch compared to pythons)

Late post, but…
Code that returns a True/False list for each item in an iterable (e.g. a list).
Replacing the brackets with parentheses returns a generator you can get values from.
Using braces returns a set. A potential replacement for all(), since sets only have 1 unique instance of each item.

What's golf?
Code golf is the concept of trying to complete a task, with as little characters in the code as possible; Kinda like how lower scores are better in golf!
