LeetCode 58. Length of Last Word

Given a string s consists of upper/lower-case alphabets and empty space characters ' ', return the length of last word in the string.

If the last word does not exist, return 0.

Note: A word is defined as a character sequence consists of non-space characters only.

For example, Given s = "Hello World",return 5.

程序代码：

int lengthOfLastWord(char* s) {    int count = 0;    int i=strlen(s)-1;    while(s[i]==' ')        i--;    while(s[i]!=' '&&i>=0)        {            count++;            i--;        }        return count;}
