I thought "a " should return 0 not 1 because after the space there is no word.
class Solution: # @param s, a string # @return an integer def lengthOfLastWord(self, s): cnt=0 for cha in s: cnt+=1 if cha == ' ': cnt=0 return cnt
class Solution: # @param s, a string # @return an integer def lengthOfLastWord(self, s): ctr = 0 temp = 0 for char in s: if char != " ": temp = temp + 1 ctr = temp elif char == " ": temp = 0 return ctr
Let's look at the note in this problem:
Note: A word is defined as a character sequence consists of non-space characters only.
Considering the example 'a ', the character after 'a' is None, but None is not a word according to the definition of 'word' in the note. So you should return the length of last word 'a'.
