Hello
Maybe it's too obvious or something everyone would have learned but I have been reading the LEBALONS problem over and over again but I am unable to comprehend this: What does expected cost of gift mean?
I don't intend to flout rules. I am not asking for test cases, hints etc. It's just the definition of the term 'expected cost' I am asking. I asked on the problem page but there's no answer yet. It would be great if a link to the definition is provided either here or in the problem page.
