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 cnt=0;
for(int i=0;i<s.length();i++)
{
if(i==0 && s[i]!=' ')
cnt++;
if(i>0 && s[i-1]==' '&& s[i]!=' ')
cnt++;
}
return cnt;
}
};
