58. Length of Last Word（LeetCode）
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.
1 class Solution { 2 public: 3 int lengthOfLastWord(string s) { 4 istringstream strcin(s); 5 string str; 6 vector<string> str1; 7 while (strcin >> str) 8 str1.push_back(str); 9 if (str1.size() == 0) 10 return 0; 11 else 12 return str1.back().size(); 13 } 14 };
