How to skip the first "n" entries in Kotlin
In this recipe, we will learn how to drop entries in a collection. First, we will see how to drop the first n items, then we will see how to drop the last n items, and finally, we will see how to use a predicate while dropping the elements from the collection.
Getting ready
I'll be using IntelliJ IDEA for writing and running Kotlin code; you are free to use any IDE that can do the same task.

In the following steps, we will learn to skip the first n entries of a Kotlin list:
- First, let's see how to drop the first n items in a collection. We will be using a list, but it also works with an array. Also, we will be using
