58. Length of Last Word

Given a string s consists of some words separated by spaces, return _the length of the last word in the string. If the last word does not exist, return _0.

A word is a maximal substring consisting of non-space characters only.

Example 1:

Input: s = "Hello World"
Output: 5

Example 2:

Input: s = " "
Output: 0

Constraints:

• 1 <= s.length <= 104
• s consists of only English letters and spaces ' '.

# @lc code=start
using LeetCode

length_of_last_word(s::String) = length(rsplit(s, ' '; limit = 2, keepempty=false)[end])
# @lc code=end
