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 ≤ 100000100 ≤ 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.
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.
