## [58. Length of Last Word](https://leetcode.com/problems/length-of-last-word/)

### 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

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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://a.b.cr/dictionary/algorithm/diary/2022/06/2022-06-23.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
