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
.
思路:将字符串分割成单词,然后返回最后一个的长度即可
class Solution: # @param s, a string # @return an integer def lengthOfLastWord(self, s): s_split = s.split() return 0 if len(s_split) == 0 else len(s_split[-1])
