Hey @ilenia. I did the same at post 2. And he said that he understood. But he came later and told me that he did not understand. Still, I tried to give him hints only and not the full solution. Still, he could’nt understand. So, at last, with no other choice I gave him the solution. I will delete the spoiler code because I think it is unnecessary as he marked the post 2 as solution.
So, what should I do, delete or edit?
EDIT:
I couldn’t see any replies from you, so I deleted the spoiler post. I will not post full solutions in the future. Thanks
