How to use drop and dropRight methods In Scala
In this approach we are using drop and dropRight method. drop method is used to remove first n elements from the collection and dropRight removes the last n elements. By calling drop(1) and dropRight(1) on the string, we remove the first and last characters, respectively.
Syntax:
str.drop(1).dropRight(1)
Example:
def removeFirstAndLast(str: String): String = {
str.drop(1).dropRight(1)
}
// Example usage:
val originalString = "Welcome to GFG"
val modifiedString = removeFirstAndLast(originalString)
println(modifiedString)
Output
elcome to GF
