Description
Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters.
Please note that the string does not contain any non-printable characters.
Example:
Input: "Hello, my name is John"
Output: 5
Solution
很简洁的写法，like it！
class Solution {
public int countSegments(String s) {
int segments = 0;
for (int i = 0; i < s.length(); ++i) {
if (s.charAt(i) != ' ' && (i == 0 || s.charAt(i - 1) == ' ')) {
++segments;
}
}
return segments;
}
}
