时间:2024-09-03 10:06:20

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-printablecharacters.

Example:

Input: "Hello, my name is John"
Output: 5
class Solution {
public int countSegments(String s) {
if (s == null || s.length() == 0) {
return 0;
}
int res = 0;
for (int i = 0; i < s.length(); i++) {
if (s.charAt(i) != ' ' && (i == 0 || s.charAt(i - 1) == ' ')) {
res += 1;
}
}
return res;
}
}
