Length of Last Word - LeetCode

PreviousCreate the longest common prefix with the direct neighbourNextCompare all possible prefixes

Last updated 9 months ago

Goal

Our goal in this chapter is to handle strings that separate words with spaces

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.

Problem Constraints

Constraints (what our possible test cases will be):

  • 1 <= s.length <= 104

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

  • There will be at least one word in s.
