Description

Given a string s consisting of words and spaces, return the length of the last word in the string.

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

Example 1:

Input: s = "Hello World"
Output: 5
Explanation: The last word is "World" with length 5.

Example 2:

Input: s = "   fly me   to   the moon  "
Output: 4
Explanation: The last word is "moon" with length 4.

Example 3:

Input: s = "luffy is still joyboy"
Output: 6
Explanation: The last word is "joyboy" with length 6.

Constraints:

  • 1 <= s.length <= 10^4

  • s consists of only English letters and spaces ' '.

  • There will be at least one word in s.

Solution

Approach #0

func lengthOfLastWord(s string) int {
    l := strings.Split(strings.Trim(s, " "), " ")
    return len(l[len(l)-1])
}
