leetcode-58 Length of Last Word

不要调用什么split之类的函数（questions like this one is intended to be a practice of detail implementation, not calling other functions）

我的code，参考了discuss

<span style="font-family:Microsoft YaHei;font-size:14px;">int lengthOfLastWord(char *s) {   int count = 0;   while(*s){       if(*s++ != ' '){           count++;       }else if(*s != '\0' && *s != ' '){           count = 0;       }   }   return count;}</span>
