Batch sequential output of numbers with pauses

It is necessary to modify the existing code so that:

• numbers from 1 to 10 are displayed in groups of five (the first set — 1‑5, the second — 6‑10);
• within each group, there is a one-second delay between printing individual numbers (this is implemented by the printNumber function);
• after completing the output of each group, a pause of two seconds should occur.

import (
        "fmt"
        "time"
        )

func main () {
    for i:= 1; i < 11; i++ {
        
    }
    
func printNumber(n int) {
        time.Sleep(time.Second)
        fmt.Println(n)        
    }
}
