No offense intended, but the negative and float cases don't make any 
sense for me on this context. You can't have -2 eggs or 0.5 eggs. The 
last case won't occure as well because the output is being parsed to 
int, so, you will get "you have 0 egg", which is again false. This error 
happens with both solutions (with > and with !=).
