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
.
class Solution {
public:
int lengthOfLastWord(const char *s) {
int cnt = 0,result = 0;
while (*s != '\0')
{
cnt = *s == ' ' 0 : cnt + 1;
result = cnt > 0 cnt : result;
s++;
}
return result;
}
};
