博客主要围绕统计字符串中片段数量展开，片段定义为连续的非空格字符序列，且字符串不包含不可打印字符，并给出示例。

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,len=s.length(),i=0;
        while(i<len){
            while(i<len&&s[i]==' '){
                i++;
            }
            if(i==len){
                break;
            }
            while(i<len&&s[i]!=' '){
                i++;
            }
            cnt++;
        }
        return cnt;
    }
};
