I am trying to prove a certain proposition on my own, and I got stuck.
I have the proof somewhere in my lecture notes, and the proposition had been proved here in some question on this site, but I do not want to see the solution because it's important for me to do it on my own.
A peek on the proof might be too much revealing, so I am looking for a tiny hint in order to complete the work.
Is it okay to ask for a hint to a problem that had already been solved here on the site?
