it's interesting to see how the answer changes with only a small change on the question:
(1 to: 100 by: 4) reject: [:i | i isOdd] gives: The code creates a collection of numbers from 1 to 100, incrementing by 4 at each step using the to:by: message. It then applies the reject: message to this collection, which returns a new collection containing all elements for which the given block evaluates to false. In this case, the block is [i | i isOdd], which checks whether a given number i is odd using the isOdd method. So the result of the entire expression is a collection of all even numbers between 1 and 100 that are divisible by 4. ciao giorgio On Wed, Mar 15, 2023 at 8:07 AM Tim Mackinnon <tim@testit.works> wrote: > Of course everyone is talking about ChatGPT, and I saw a post to > ExplainCode and didn’t expect it to understand Smalltalk, so was impressed > that it does!
