Write a method that returns the number of 'increasing' characters at the start of string 'str'. To be increasing characters, each successive character must have a higher UNICODE value than the previous character. For example, in "abdfjknz" ALL characters are in increasing character order since the UNICODE for 'b' is greater than the UNICODE for 'a'; the UNICODE for 'd' is greater than the UNICODE for 'b', etc. Suggestion: Use the charAt method! Remember: This is looking for the number of increasing characters starting at the beginning of the string. This is NOT looking for the longest sequence of increasing character starting anywhere. It IS looking for the longest sequence of increasing characters, starting at the beginning of the string. Hint: When you compare characters with the "<" or ">" comparison, it automatically compares their UNICODE values! Another hint: Look at the test data for examples!
