### Prompt

In Cpp, your task is to solve the following problem:

You are given a matrix n × m, initially filled with zeroes. We define a_{i, j} as the element in the i-th row and the j-th column of the matrix.

Two cells of the matrix are connected if they share a side, and the elements in these cells are equal. Two cells of the matrix belong to the same connected component if there exists a sequence s_1, s_2, ..., s_k such that s_1 is the first cell, s_k is the second cell, and for every i ∈ [1, k - 1], s_i and s_{i + 1} are connected.

You are given q queries of the form x_i y_i c_i (i ∈ [1, q]). For every such query, you have to do the following:

  1. replace the element a_{x, y} with c; 
  2. count the number of connected components in the matrix. 



There is one additional constraint: for every i ∈ [1, q - 1], c_i ≤ c_{i + 1}.

Input

The first line contains three integers n, m and q (1 ≤ n, m ≤ 300, 1 ≤ q ≤ 2 ⋅ 10^6) — the number of rows, the number of columns and the number of queries, respectively.

Then q lines follow, each representing a query. The i-th line contains three integers x_i, y_i and c_i (1 ≤ x_i ≤ n, 1 ≤ y_i ≤ m, 1 ≤ c_i ≤ max(1000, ⌈ (2 ⋅ 10^6)/(nm) ⌉)). For every i ∈ [1, q - 1], c_i ≤ c_{i + 1}.

Output

Print q integers, the i-th of them should be equal to the number of components in the matrix after the first i queries are performed.
