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
class Solution {
public int countSegments(String s) {
int segmentCount = 0;
for (int i = 0; i < s.length(); i++) {
if ((i == 0 || s.charAt(i-1) == ' ') && s.charAt(i) != ' ') {
segmentCount++;
}
}
return
