apcsaChatbotsCountWordsHard


HARDER PROBLEM: skip if you have trouble
Given an input String, find the number of words. For this problem, a word is defined very simply as any set of characters which are not spaces. The test cases for this problem include more "edge cases" with more unusual character sequences. 

HINT: think about how many spaces there are in the input.

apcsaChatbotsCountWordsHard(" spacefirst") → 1
apcsaChatbotsCountWordsHard("spacelast ") → 1
apcsaChatbotsCountWordsHard("nospace") → 1
...Save, Compile, Run (ctrl-enter)
public int apcsaChatbotsCountWordsHard(String str) {
  
}
