How can I use Go to rearrange a list of words into a traditional Japanese poetry form, with the following format: 
First line: one word
Second line: three words
Third line: five words
Here is the list of words:
["Sky", "High", "love", "grows", "Sun", "sets", "my", "for", "you"]
Please provide a sample code in Go for this task.

Sure, here's how you could do it in Go. This code will create a function `rearrange` that takes a string slice as input and returns a restructured poem with a list of lines in the required format. It checks if the length of the slice is valid for the provided format before rearranging and returning it.

```go
package main

import (
	"fmt"
	"strings"
)

func main() {
	words := []string{"Sky", "High", "love", "grows", "Sun", "sets", "my", "for", "you"}

	poem := rearrange(words)

	for _, line := range poem {
		fmt.Println(line)
	}
}

func rearrange(words []string) []string {
	if len(words) != 4 {
		return nil // If the words do not follow the given format, return nil.
	}

	var line1 string
	var line2 []string
	var line3 []string

	for _, word := range words {
		switch len(word) {
		case 1:
			if len(line1) > 0 {
				line2 = append(line2, line1)
				line1 = word
			} else {
				line1 = word
			}
		case 3:
			line2 = append(line2, word)
		case 5:
			if len(line3) > 0 {
				line2 = append(line2, line3)
				line3 = []string{word}
			} else {
				line3 = []string{word}
			}
		}
	}

	if len(line2) > 0 {
		line2 = append(line2, line1)
		line1 = ""
	}

	if len(line3) > 0 {
		line2 = append(line2, line3)
		line3 = nil
	}

	if len(line1) > 0 {
		line2 = append(line2, line1)
		line1 = ""
	}

	var result []string
	if len(line2) > 0 {
		result = append(result, strings.Join(line2, " "))
	}
	if len(line3) > 0 {
		result = append(result, strings.Join(line3, " "))
	}

	return result
}

Sure, here's a sample Go code that rearranges the given list of words into the desired format:

```go
package main

import (
	"fmt"
	"strings"
)

func main() {
	words := []string{"Sky", "High", "love", "grows", "Sun", "sets", "my", "for", "you"}

	// Check if the number of words is correct
	if len(words) != 9 {
		fmt.Println("Invalid number of words. Expected 9, got", len(words))
		return
	}

	// Rearrange the words into the desired format
	poem := []string{
		words[0],
		strings.Join(words[1:4], " "),
		strings.Join(words[4:], " "),
	}

	// Print the poem
	for _, line := range poem {
		fmt.Println(line)
	}
}
```

When you run this code, it will print:

```
Sky
High love grows
Sun sets my for you
```

This code first checks if the number of words is correct. Then it rearranges the words into the desired format and prints the resulting poem. The `strings.Join` function is used to join multiple words into a single string with a space character as the separator.
