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 i,j; for(i=strlen(s)-1;i>=0;i--)if(s[i]!=‘ ‘)break; for(j=i;j>=0;j--)if(s[j]==‘ ‘)break; return i-j; } };
