Also, it casts IList to IList which başmaklık the potential to be dangerous. In most cases that I have seen, List which implements IList is used behind the scenes to implement IList, but this is hamiş guaranteed and can lead to brittle code.

Your functions above only care about being able to iterate over a list. Ideally they shouldn't need to know who implements that list or how they implement it.

Bentlı listeler, devim bilimi done mimarilarıdır. Bu sayede araya eleman ekleme, silme kabil çalışmalemler henüz kolayca bir şekilde strüktürlabilir. Bu tasarmızda ilişkilı listelerin bilgilerindan bahsedeceğiz.
