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: 823. Binary Trees With Factors_test.go
    path of file: ./repos/LeetCode-Go/leetcode/0823.Binary-Trees-With-Factors
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question823 struct {
	para823
	ans823
}

// para 是参数
// one 代表第一个参数
type para823 struct {
	arr []int
}

// ans 是答案
// one 代表第一个答案
type ans823 struct {
	one int
}

			ans823{3},
		},

		{
			para823{[]int{2, 4, 5, 10}},

	}

	fmt.Printf("------------------------Leetcode Problem 823------------------------\n")

	for _, q := range qs {
