The program capitalizes the first letter of each reversed word in a sentence.

Split the sentence into an array of words using space as a delimiter.
Reverse each word in the array and capitalize the first letter.
Join the modified words back into a sentence.

Accepted Answer

fun main(args: Array) {
val ip = "how are you ?"
val ipArr = ip.split(" ")
val result = mutableListOf()
ipArr.forEach { index->
val reverse = reverse(index, "")

result.add(reverse[0].uppercase()+reverse.substring(1))
}

println(result.joinToString { it }.replace(",", ""))
}

fun reverse(ip: String, op: String): String {
if(ip.length == 0) {
return op
}
return reverse(ip.substring(1), ip[0]+op)
}
