Difficulty: EASY

Today is Kriti's birthday but I forgot to bring a gift for her. She is very angry with me. I have an idea for a gift. She likes coding very much. Why not give her a problem to solve as her gift?

I know a problem but I am not sure whether its solvable or not.

The problem initially has N strings numbered 1 to N. The program has to answer Q queries. Each query is of the form l r S.  For each query, the program has to print the number of times the string S appears in the range [l,r].Help me by solving the problem!!
Input

Input will begin with an integer N denoting the number of strings.
N lines follows each having a string. 
The next line contains Q denoting the number of queries.
Each of the next Q lines contain a query of the form l r S.

 Output

For each query of type l r S, print the answer to that query. Each answer must be in a new line.

Constraints

100 ≤ N ≤ 100000
100 ≤ Q ≤ 100000
1 ≤ l ≤ r ≤ N 
Size of each string in the input is greater than or equal to 5 and less than or equal to 10.
Each string contains only lower case english characters.
SAMPLE INPUT
3
abc
def
abc
3
1 2 abc
1 3 abc
1 2 hgj

SAMPLE OUTPUT
1
2
0

Explanation

For query 1:
Only one "abc"  is present (at position 1st)  in the range [1,2], so the answer is 1.
For query 2:
Two "abc" are present (at position 1 and at position 3), so the answer is 2.
For query 3:
No "hgf" is present in the range [1,2], so the answer is 0.


N=int(input())
strings=dict()
for i in range(N):
	s=input()
	if(s in strings):
		strings[s].append(i+1)
	else:
		strings[s]=[i+1]
		
Q=int(input())


for i in range(Q):
	l,r,query=input().split()
	l=int(l)
	r=int(r)
	cnt=0

	if query in strings:
		a=strings[query]
		cnt=sum([1 for x in a if x>=l and x<=r])
			
	
	print(cnt)
