Instructions
Write a function that returns 'true' if the 'string' passed as parameter contains only the uppercase characters; returns 'false' otherwise.
Expected function
func IsUpper(s string) bool {
}
Usage
Here is a possible program to test your function :
package main

func main() {
fmt.Println(piscine.IsUpper("HELLO"))
fmt.Println(piscine.IsUpper("HELLO!"))
