How do you compare two sequences using LINQ? The answer is by using the Enumerable.SequenceEqual(). SequenceEqual() compares the source and target sequences elements, by using the default equality comparer for their type, and returns a Boolean.

The output will be: False
Now what if you want to find out the difference between these two sequences?. Use this piece of code which uses the IEnumerable.Except extension method:
