You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 409. Longest Palindrome_test.go
    path of file: ./repos/LeetCode-Go/leetcode/0409.Longest-Palindrome
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question409 struct {
	para409
	ans409
}

// para 是参数
//
    
func Test_Problem409(t *testing.T) {

	qs := []question409{

		{
			para409{"abccccdd"},
			ans409{7},
		},
	}

	fmt.Printf("------------------------Leetcode Problem 409------------------------\n")

	for _, q := range qs {
		_, p := q.ans409, q.para409
		fmt.Printf("【input】:%v       【output】:%v\n", p, longestPalindrome(p.one))
	}
	fmt.Printf("\n\n\n")
}
