import java.util.Scanner;

public class Solution {
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);

		int t = sc.nextInt();

		for (int tc = 1; tc <= t; tc++) {

			int n = sc.nextInt();
			String target = sc.next();
			String word = sc.next();

			int count = 0;

			for (int i = 0; i < target.length(); i++) {
				if (target.charAt(i) == word.charAt(i)) {
					count++;
				}
			}

			System.out.println("#" + tc + " " + count);

		}

	}
}

 

.charAt 함수를 사용하여 비교해주면 되는 간단한 문제이다.
