AC代码：

#include<cstdio>
#include<cstring>

int n, m;
char x[7][4];
char s[1<<7], s2[1<<7];

int main() 
	#ifdef LOCAL
	freopen("input.txt", "r", stdin);

	#endif
	int kase = 0;
	while(scanf("%d", &n) == 1 && n) 
		printf("S-Tree #%d:\\n", ++kase);
		for(int i = 0; i < n; i++) scanf("%s", x[i]);
		scanf("%s", s);
		scanf("%d", &m);
		while(m--) 
			scanf("%s", s2);
			int len = strlen(s2);
			int k = 1;
			for(int i = 0; i < len; i++)

				else k = 2*k;
			
			printf("%c", s[k-(1<<n)]);
		
		printf("\\n\\n");
