Method of splitting strings using uncertain number of spaces in Golang

Use the function

The function accepts a string-type parameter, uses spaces and multiple consecutive spaces to split the string, and returns a string slice, which just meets our needs. Examples of use are as follows:

package main
import (
	"fmt"
	"strings"
)
func main() {
	str := "Welcome to Ludosin's blog What Is Great"
	s := (str)
	(s)
}

Run to see the effect:

$ go run
[Welcome to Ludosin's blog What I think is great]

It can be seen that although the substrings in str are separated by spaces of varying numbers, a slice of string type is obtained after processing using the function, and the string is perfectly divided.

Using regular expressions

First look at the sample code:

package main
import (
	"fmt"
	"regexp"
)
func main() {
	str := "Welcome to Ludosin's blog What Is Great"
	reg := (`\s+`)
	result := (str, -1)
	(result)
}

Run to see the effect:

$ go run
[Welcome to Ludosin's blog What I think is great]

Get the same data as in the previous example, first use the function to create a regular expression to match one or more spaces (\s+ means to match at least one space character). Then use the   method to split the string, and the second parameter -1 means that all substrings are returned.
