Well, I'm doing a job for college where I need to identify the number of words a string has in Kotlin.

Type:

texto = "Ola Mundo"

The variable numeropalavra s must be equal to 2.

Is there a function that checks the number of words, without having to cycle to check the letter to find the number of words?

You can separate the string by the spaces between the words using the split() function and see the length (length) of the array.

val string = "Uma string de exemplo"
val numeropalavras = string.split().length
