💡 Hint

Common Mistakes

Not using alias syntax correctly.

Importing "math/rand" without alias when alias is needed.

You import "fmt" normally and alias "math/rand" as "random" using the syntax: alias "package".

Fill all three blanks to import "fmt", alias "math/rand" as "random", and import "time" package.

Go

package main

import (
    [1]
    [2]
    [3]

func main() {
    fmt.Println(random.Intn(100))
    fmt.Println(time.Now())
}

Drag options to blanks, or click blank then click option'
