How to display post/category path in a template?

Hi all.
I have few questions, but let’s start with the first one.
Part of a sitemap (my categories):
-Memories // category
— Diaries // category
— Poems // category
—- O stars //single post in it

I want to display a line with the following content:
– “You are here: Memories” if I am on the category page “memories”
– “You are here: Memories > Diaries” if I am on the category page “diaries”
– “You are here: Memories > Diaries > Poems” if I am on the category page “poems”
– “You are here: Memories > Diaries > Poems > O stars” if I am on the single post page with the post title “o stars”

Is there any way to do it? Plugin or php, I don’t care pretty much.
PS. I’m using only categories for my blog navigation, no pages
