//判斷父字符串是否包含子字符串，包含為真，否則為假
fmt.Println("-------------------------------")

//子字符串在父字符串中出現的次數
fmt.Println("-------------------------------")
fmt.Println("Count Function: ",strings.Count("Australia", "lia"))
fmt.Println("Count Function: ",strings.Count("Australia", "A"))

//判斷子字符串是否為父字符串的前綴
fmt.Println("-------------------------------")
fmt.Println("HasPrefix Function: ",strings.HasPrefix("Australia", "Bu"))
fmt.Println("HasPrefix Function: ",strings.HasPrefix("Australia", "Aus"))
////判斷子字符串是否為父字符串的後綴
fmt.Println("-------------------------------")
fmt.Println("HasSuffix Function: ",strings.HasSuffix("Australia", "lia"))
fmt.Println("HasSuffix Function: ",strings.HasSuffix("Australia", "tia"))
//子字符串首次出現在父子符串的索引下標
fmt.Println("-------------------------------")
fmt.Println("Index Function:",strings.Index("Australia", "lia"))
fmt.Println("Index Function: ",strings.Index("Australia", "a"))
fmt.Println("Index Function: ",strings.Index("Australia", "A"))
//連接函數，指定分隔符將字符串連接起來
fmt.Println("-------------------------------")
fmt.Println("Join Functions:",strings.Join([]string{"Austrilia", "Japen", "Germany"}, "-"))
fmt.Println("Join Function: ",strings.Join([]string{"Australia","Japan","Germany"}," "))
//重復函數，指定字符串重復出現的次數
fmt.Println("-------------------------------")
fmt.Println("Repeat Function:", strings.Repeat("Australia",3))
//替換字符串函數，
fmt.Println("-------------------------------")
fmt.Println("Replace Function: ",strings.Replace("Australia ","a","b",1))

//分割函數，指定分隔符分隔字符串
fmt.Println("-------------------------------")
fmt.Println("Split Function:", strings.Split("Australia-Japan-Germany","-"))
//把字符轉小寫
fmt.Println("-------------------------------")
