Nobody?
What you have written does not look like a linear algorithm. To understand what is wrong with it, please explain as clearly as you can (at least to yourself) what the lines 63 – 71 do and — specifically — what purpose the variable S serves.
Isn't it just a stack, that will have at most n elements pushed and hence at most n elements popped?
My bad, I somewhy thought that the array vis is used to call dfs(u).
It's an implementation of Tarjan's algorithm taken from Competitive Programming 3 book.
I will comment my codes for future questions. Thanks
stupid site -_-, I'm still waiting for some judge ID to submit the problem !!
I know, I hate this online judge
Oh, but it passes :). Just change cin,cout to scanf,printf and send to Visual C++ 2010 B-). For some reason other combinations don't work.
Thanks, it passed. I don't understand why it was giving me WA. I hate this judges
