### Instructions

### Expected functions
|

||
|
|

||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|

Here is a program to test your function.
|
||
|
|
|
||
|
|
```go
|
||
|
|
package main
|
||
|
|
|
||
|
|
import (
|
||
|
|
"fmt"
|
||
|
|
)
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
fmt.Println(CountAlpha("Hello world"))
|
||
|
|
fmt.Println(CountAlpha("H e l l o"))
|
||
|
|
fmt.Println(CountAlpha("H1e2l3l4o"))
|
||
|
|
}
|
||
|
|
```
