As you know Chef likes problems which involving into newest data structures. Today he has troubes in solving tricky problem. You have array A consisting of N integers and Q queries to it. Queries are next: - L R K, how many values in segment A[L..R] have frequency not more than K.
The first line of input contains T - number of test cases. T test cases follow.
For each test case, first line contains an integer N - number of elements in array, and integer Q - number of queries to it.
Second line contains N positive integer numbers - elements of array A. Each of next Q lines containing three integers L, R, K.
For each query output answer for it in separate line.
- 1 ≤ T, N, Q, sum over all values of N in the input, sum over all values of Q in the input ≤ 200,000
- 1 ≤ Ai ≤ 109
- 1 ≤ L ≤ R ≤ N
- 1 ≤ K ≤ N
Input: 1 5 3 1 2 3 2 1 2 4 2 1 5 1 1 5 2 Output: 2 1 3
