Given an input String, find the number of spaces. 


HINT: use a loop that examines each character and either str.substring(i, i+1).equals(" ") or str.charAt(i) == ' ' to find the spaces.


CHALLENGE: Solve this in one statement.

apcsaChatbotsNumSpaces("Hello world") → 1
apcsaChatbotsNumSpaces("Hello to the world") → 3
apcsaChatbotsNumSpaces("If I am gone") → 3
...Save, Compile, Run (ctrl-enter)
public int apcsaChatbotsNumSpaces(String str) {
  
}
