Re: [racket-users] Funtional programming and the maximum of something

A clue to the answer is in your statement that you "feed that [maximum] into the next circle of recursion." Notice that you're not overwriting the value in the current call, you're creating a new value that you feed into the new call in the "next circle". So the old one isn't being overwritten at

Re: [racket-users] Funtional programming and the maximum of something

I'm not sure if I understand what you're tying to do correctly, but here's one way to do it (or one way to do something, at least): (define (process-list-of-lists list-of-lists) (apply map (λ args (apply max args)) list-of-lists)) (process-list-of-lists

Re: [racket-users] Funtional programming and the maximum of something

You need to follow the design recipe to solve a problem like this. You data is clear: [Listof [Listof Real]] and [Listof Real]. Next up: examples. Do you have examples of the inputs and outputs you want for this function? Robby On Sat, Oct 22, 2016 at 2:03 PM, wrote: > Hi,

Hi, (I am still a newbie ... ) If I remember one rule of functional programming correctly, it says: Instead of changeing data - create new data. Suppose I have a list of list. Each "sublist" is made of a greater amount (but identical count) of exact numbers (integers). I want to process
