Hello,

I'm working on a discrete mathematics for computing paper and am stuck on what a symbol is trying to convey. Sorry if this seems like a stupid question (I feel stupid for not being able to work it out myself), I've just started this subject and am still getting used to it.

My question is what does the Xc mean in this algorithm (picture attached)? I understand that X1, X2 etc are the different variables, but does the Xc have something to do with the variable C := 1? If so, what does that symbol mean? I.e. what am I supposed to do with the variable in relation to C?

I hope this is clear enough and that once it's been explained to me I can crack on with the paper. Thank you very much in advance.
