alpha-position
Instructions
Write a function named AlphaPosition
that takes an alphabetical character as a parameter and returns the position of the letter in the alphabet.
- If the character is not in the alphabet, return -1
- If the character is in the alphabet, return the position of the letter in the alphabet
Expected function
func AlphaPosition(c rune) int {
// your code goes here
}
Usage
Here is a possible program to test your function:
package main
import "fmt"
func main(){
fmt.Println(AlphaPosition('a'))
fmt.Println(AlphaPosition('z'))
fmt.Println(AlphaPosition('B'))
fmt.Println(AlphaPosition('Z'))
fmt.Println(AlphaPosition('0'))
fmt.Println(AlphaPosition(' '))
}
And its output :
$ go run . | cat -e
1$
26$
2$
26$
-1$
-1$
