Merging a List of Strings in Scala

To merge a list of strings in Scala, you can use the mkString method. This method concatenates all the elements of the list into a single string, with an optional separator between each element.

Here's an example of how to merge a list of strings in Scala:

val list = List("Hello", "World", "!")
val mergedString = list.mkString

// Output: HelloWorld!

By default, the mkString method concatenates the elements without any separator. However, you can specify a separator by passing it as an argument to the mkString method. For example:

val list = List("Hello", "World", "!")
val mergedString = list.mkString(" ")

// Output: Hello World !

In the above example, the space character " " is used as the separator between the elements.

That's it! You can use the mkString method to merge a list of strings in Scala.
