// strings.Fields() Function 
package main 
    
import ( 
    "fmt"
    "strings"
) 
    
func main() {    
               
    // String s is split on the basis of white spaces 
    // and store in a string array 
    s:= "GeeksforGeeks is a computer science portal !"
    v:= strings.Fields(s) 
    fmt.Println(v)      
       
    // Another example by passing the string as argument 
    // directly to the Fields() function
