Question

str.replace( /  +/g, ' ' ).split(' ').length

Faster would be with a loop and no regex. But that depends on large your str is

Sigiloso · Answer

var t = input.trim //eliminates any extra spaces at the start of the sentences,which will introduce 
                                       //extra word count
 val r = t.split(' ').length
 println(r)

Still this is incomplete in itself as this will fail in the case like
" hello my     name is xyz"
as there are few extra spaces in between "my" and "name"

def count_words(str):
	return len(str.split())
