##WARNING! VERY IMPORTANT!
For this exercise a function will be tested with the exam own main. However the student still needs to submit a structured program:
This means that:
- The package needs to be named
package main. - The submitted code needs one declared function main(
func main()) even if empty. - The function main declared needs to also pass the
Restrictions Checker(illegal functions tester). It is advised for the student to just empty the function main after its own testings are done. - Every other rules are obviously the same than for a
program.
Instructions
Write a function that returns the nth rune of a string.
- In case of impossibilities, the function returns
0.
Expected function
func NRune(s string, n int) rune {
}
Usage
Here is a possible program to test your function :
package main
import (
"github.com/01-edu/z01"
piscine ".."
)
func main() {
z01.PrintRune(piscine.NRune("Hello!", 3))
z01.PrintRune(piscine.NRune("Salut!", 2))
z01.PrintRune(piscine.NRune("Bye!", -1))
z01.PrintRune(piscine.NRune("Bye!", 5))
z01.PrintRune(piscine.NRune("Ola!", 4))
z01.PrintRune('\n')
}
And its output :
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test
la!
student@ubuntu:~/[[ROOT]]/test$
