02. Greater Number

package main
import "fmt"

func main() {
    var num1, num2 int
    fmt.Scanln(&num1)
    fmt.Scanln(&num2)

    if (num1 > num2) {
        fmt.Println(num1)
    } else {
        fmt.Println(num2)
    }
}

ИЛИ:

package main
import (
    "fmt"
    "math"
)

func main() {
    var num1, num2 float64
    fmt.Scanln(&num1)
    fmt.Scanln(&num2)

    fmt.Println(math.Max(num1, num2))
}
