func Nth

func Nth(input int) (int, error)

Nth returns the nth prime number. An error must be returned if the nth prime number can't be calculated ('n' is equal or less than zero)

Example

{
	cases := []int{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

	for _, i := range cases {
		p, e := Nth(i)
		fmt.Printf("%d: %d:%v\n", i, p, e)
	}

}

Output

0: 0:the nth prime has to be equal to or greater than 1
1: 2:<nil>
2: 3:<nil>
3: 5:<nil>
4: 7:<nil>
5: 11:<nil>
6: 13:<nil>
7: 17:<nil>
8: 19:<nil>
9: 23:<nil>
10: 29:<nil>
