KQUERY - K-query

no tags 

Given a sequence of n numbers a1, a2, ..., an and a number of k- queries. A k-query is a triple (i, j, k) (1 ≤ i ≤ j ≤ n). For each k-query (i, j, k), you have to return the number of elements greater than k in the subsequence ai, ai+1, ..., aj.

Input

  • Line 1: n (1 ≤ n ≤ 30000).
  • Line 2: n numbers a1, a2 ... an (1 ≤ ai ≤ 109).
  • Line 3: q (1 ≤ q ≤ 200000), the number of k- queries.
  • In the next q lines, each line contains 3 numbers i, j, k representing a k-query (1 ≤ i ≤ j ≤ n, 1 ≤ k ≤ 109).

Output

  • For each k-query (i, j, k), print the number of elements greater than k in the subsequence ai, ai+1 ... aj in a single line.

Example

Input

5 1 2 3 4
3
2 4 1
4 4 4
1 5 2 

Output

You can use square root decomposition here and merge sort trees as well.

Needed C++ Fast IO for atleast one approach
