Number of Segments in a String

Posted 2020-08-30 amazingzoe

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

 

 1 public class Solution {
 2     public int countSegments(String s) {
 3         int result = 0;
 4         
 5         int i = 0, n = s.length();
 6         while (i < n) {
 7             if (s.charAt(i) != ‘ ‘) {
 8                 while (i < n && s.charAt(i) != ‘ ‘) i++;
 9                 result++;
10             }
11             
12             while (i < n && s.charAt(i) == ‘ ‘) i++;
13         }
14         return result;
15     }
16 }
