infinite loop

Question

why is there an infinite loop if I did't put in the break? Shouldn't it only go once with the numbers in the set once only since it is a for loop

Answer 1

Nevermind, just realised I have been adding values into the set, causing it to loop over the new values again and my solution is to use another set for the second part
