Background Check out this video on the Collatz conjecture, also known as A006577. If you don't know what this is, we're given an equation of $3x + 1$, and it is applied this way: If $x$ is odd...
Challenge Make a program that takes input of 3 non-negative integers: a result and 2 other values that once calculated results to the 3rd value. The program must figure out how to get the 2 fir...

I have seen KOTH (King of the Hill) challenges before but it's still unclear to me how to properly make, or even play, such challenge. To get started, how do I make (or solve) KOTHs? An answer cou...

Introduction What is the Caesar shift cipher (ROT$n$)? It's basically a cipher sequence that changes a letter's value from the number chosen. If we use ROT1 on "games", we get "hbnft". The basic i...

I have this challenge in Code Golf and I wonder if I can repost it here for more users to come, and also continue making these since I actually like them. Can I post this challenge to Codidact?
Use for(;;) instead of while(true) The title's self-explanatory. A byte saver.
Use a+=[b] instead of a.append(b) The title says it all. a=[];b=10;print(a) a+=[b];print(a) Try it online!
