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: 643. Maximum Average Subarray I_test.go
    path of file: ./repos/LeetCode-Go/leetcode/0643.Maximum-Average-Subarray-I
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question643 struct {
	para643
	ans643
}

// para 是参数
// one 代表第一个参数
type para643 s
    
func Test_Problem643(t *testing.T) {

	qs := []question643{

		{
			para643{[]int{1, 12, -5, -6, 50, 3}, 4},
			ans643{12.75},
		},
	}

	fmt.Printf("------------------------Leetcode Problem 643------------------------\n")

	for _, q := range qs {
		_, p := q.ans643, q.para643
		fmt.Printf("【input】:%v       【output】:%v\n", p, findMaxAverage(p.nums, p.k))
	}
	fmt.Printf("\n\n\n")
