import java.util.Scanner;

class Main {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		sc.nextLine();
		int a[] = new int[n];
		for (int i = 0; i < a.length; i++) {
			a[i] = sc.nextInt();
		}
		sc.nextLine();
		int m = sc.nextInt();
		for (int i = 0; i < a.length; i++) {
			if (a[i] == m) {
				System.out.println(i + 1);
				return;
			}
		}
		System.out.println(-1);
