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