var scoreMapping = map[rune]int{

	69: 1,
	73: 1,
	79: 1,
	85: 1,
	76: 1,

	89: 4,
	75: 5,
	74: 8,
	88: 8,
	81: 10,
	90: 10,
}

// Score function calculate string parameter's point base on scoreMapping
func Score(input string) int {
	result := 0
	inputUpper := strings.ToUpper(input)
	for _, s := range inputUpper {
		result += scoreMapping[s]
	}
	return result
}

And you can also define map[rune]int like follow:

var scoreMapping = map[rune]int{
  'A': 1,
  'E': 1,
...
