Count the number of segments in a string. A segment is a contiguous sequence of non-space characters. Return 0 for null input and 0 for an empty or whitespace-only string.
Examples:
Input: str = 'Hello, my name is John'
Output: 5
Explanation: There are 5 segments separated by spaces
Input: str = 'love'
Output: 1
Explanation: A single word with no spaces is one segment
Input: str = ''
Output: 0
Explanation: Empty string has no segments
