Nested set model vs recursion

>>62400274

is this comp-sci 101?

when is recursion ever good?

>>62400308
Quickly programming something.

>>62400308
When you don't have a mapping of what you need to display.

A good example is drop down navigation on a website. Especially when you have more than two levels.

>>62400308
When dealing with recursive data structures like trees

>>62400329
faggots and haskellors(faggots) use recursion
>>62400367
you're a fucking idiot
>>62400420
you're a fucking retard

make a traversing loop instead

>>62401636
Why make it more difficult to understand with a loop? Recursion with memoization is clean, fast, and simple.

>>62401636
>hurr durr just use a traversing loop
And waste 25 lines doing what could be done in 3? If you use a language that uses tail call optimization then it literally doesn't matter. You're such a brainlet
