Kotlin program to reverse a sentence using recursion

Kotlin Comprehensive Examples

In this program, you will learn how to use recursion in Kotlin to reverse a given sentence.

Example: Using recursion to reverse a sentence

fun main(args: Array<String>) {
　　　　val sentence = "Go work"
　　　　val reversed = reverse(sentence)
　　　　println("The reversed sentence is: $reversed")
}
fun reverse(sentence: String): String {
　　　　if (sentence.isEmpty())
　　　　　　　　return sentence
　　　　return reverse(sentence.substring(1))　+　sentence[0]
}

When the program is run, the output is:

The reversed sentence is: KROW OG

In the above program, we have a recursive function reverse().

This is the equivalent Java code:Java Program to Reverse Sentences
