Question: Write a method wordCount which takes a string and returns the number of words in it. You may assume that the string contains only letters,

Write a method wordCount which takes a string and returns the number of words in it. You may assume that the string contains only letters, digits, punctuation, or spaces. You may also assume that words are always separated by spaces. If two words are separated by multiple spaces, they still are only two words (so you cannot just count the number of spaces!). Everything that is not a space, including digits and punctuation, is considered part of a word. For this problem, you are not allowed to use the method split() which is available for String objects in Java.

Examples:

wordCount("This is a test") returns 4

wordCount("") returns 0

wordCount("Wahoo42!??!?!") returns 1

wordCount("This is a test!!!!!") returns 4
