`Easy`	`Codewriting` 	`300`

Check if all digits of the given integer are even.

## Example

- For `n = 248622`, the output should be
`evenDigitsOnly(n) = true`;

- For `n = 642386`, the output should be
`evenDigitsOnly(n) = false`.

## Input/Output

- [execution time limit] 4 seconds (go)

- [input] integer n

    Guaranteed constraints: \
    `1 ≤ n ≤ 109`.

- [output] boolean

    `true` if all digits of n are even, `false` otherwise.

## [Go] Syntax Tips

``` go
// Prints help message to the console
// Returns a string
func helloWorld(name string) string {
    fmt.Printf("This prints to the console when you Run Tests");
    return "Hello, " + name;
}
```
