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: 1742. Maximum Number of Balls in a Box_test.go
    path of file: ./repos/LeetCode-Go/leetcode/1742.Maximum-Number-of-Balls-in-a-Box
    
    the code of the file until where you have to start completion: package leetcode

import (
	"fmt"
	"testing"
)

type question1742 struct {
	para1742
	ans1742
}

// para 是参数
// one 代表第一个参数
type para1742 struct {
	lowLimit  int
	highLimit int
}
    
func Test_Problem1742(t *testing.T) {

	qs := []question1742{

		{
			para1742{1, 10},
			ans1742{2},
		},

		{
			para1742{5, 15},
			ans1742{2},
		},

		{
			para1742{19, 28},
			ans1742{2},
		},
	}

	fmt.Printf("------------------------Leetcode Problem 1742------------------------\n")

	for _, q := range qs {
		_, p := q.ans1742, q.para1742
		fmt.Printf("【input】:%v       【output】:%v\n", p, countBalls(p.lowLimit, p.highLimit))
	}
	fmt.Printf("\n\n\n")
