package main
import "fmt"
var pow = []int{1, 2, 4, 8, 16, 32, 64, 128}
func main() {
    for i, v := range pow {
        fmt.Printf("2**%d = %d\n", i, v)
    }
}

package main
import "fmt"
func main() {
    pow := make([]int, 10)
    for i := range pow {
        pow[i] = 1<<uint(i)
    }
    for _, value := range pow {
        fmt.Printf("%d\n", value)

}
