Decimal number = 2737

Input: hexadecimal num = 12
Decimal number = 18

Input: hexadecimal num = ffff
Decimal number = 65535

Code:

func main() {

  hex_num := "ab1"

  num, err := strconv.ParseInt(hex_num, 16, 64)

  if err != nil {

    panic(err)

  }

  fmt.Println("decimal num: ", num)


  hex_num = "12"

  num, err = strconv.ParseInt(hex_num, 16, 64)

  if err != nil {

    panic(err)

  }

  fmt.Println("decimal num: ", num)


  hex_num = "ffff"

  num, err = strconv.ParseInt(hex_num, 16, 64)

  if err != nil {

    panic(err)
