Remove leading and trailing whitespace in Kotlin

Sure! In Kotlin, you can use the trim() function to remove leading and trailing whitespaces from a string. Here's how:

Example 1:

val str1 = "  Hello World  "
val trimmedStr1 = str1.trim()
println(trimmedStr1) // Output: "Hello World"

In this example, the original string str1 contains leading and trailing whitespaces. The trim() function is called on the string, which returns a new string with the leading and trailing whitespaces removed. The resulting string is stored in the variable trimmedStr1, and when printed to the console, it outputs "Hello World" with no leading or trailing whitespaces.

Example 2:

val str2 = "  Kotlin is awesome!   "
val trimmedStr2 = str2.trim()
println(trimmedStr2) // Output: "Kotlin is awesome!"

This example works the same way as the first one, but the original string str2 contains a mix of leading and trailing whitespaces. The trim() function is again used to remove these whitespaces, and the resulting string is stored in the variable trimmedStr2. When printed to the console, it outputs "Kotlin is awesome!" with no leading or trailing whitespaces.
