从不上面的测试内容来看,使用strings.Join方法是实现效果最好的方法,耗时是最低的,内存占用也最低,额外内存分配次数也只有1次,我们查看strings.Join的方法内部的实现代码。 // Join concatenates the elements of its first argument to create a single string. The separator // string sep is placed between ele...
The separator string is placed between elements in the resulting string. fmt_funs.go package main import ( "fmt" "strings" ) func main() { words := []string{"an", "old", "falcon"} msg := strings.Join(words, " ") fmt.Println(msg) } ...
下面是一些具体的例子,展示了如何使用strings.Join函数。 示例1:基本用法 package main import ( "fmt" "strings" ) func main() { list := []string{"apple", "banana", "cherry"} separator := ", " result := strings.Join(list, separator) fmt.Println(result) // 输出: apple, banana, cherry...

Go string Join/SplitThe strings.Join function concatenates the elements of its first argument to create a single string, while the strings.Split function slices the given string into all substrings separated by the provided separator and returns a slice of the substrings. join_split.go ...

从本机来看通过+号连接字符串每个操作消耗127ns时间,strings.Join消耗78.7ns。效率上strings.Join更高 来看下strings包中Join的实现 // Join concatenates the elements of a to create a single string. The separator string// sep is placed between elements in the resulting string.funcJoin(a []string, sep...
