findnextprime
Instructions
Write a function that returns the first prime number that is equal or superior to the int passed as parameter.
The function must be optimized in order to avoid time-outs with the tester.
(We consider that only positive numbers can be prime numbers)
Expected function
func FindNextPrime(nb int) int {
}
Usage
Here is a possible program to test your function :
package main
import (
"fmt"
"piscine"
)
func main() {
fmt.Println(piscine.FindNextPrime(5))
fmt.Println(piscine.FindNextPrime(4))
}
And its output :
$ go run .
5
5
$
