Multidimensional Queries
You are given an array a of n points in k-dimensional space. Let the distance between two points a_x and a_y be ∑ {i = 1}^{k} |a{x, i} - a_{y, i}| (it is also known as Manhattan distance).
You have to process q queries of the following two types:
- 1 i b_1 b_2 ... b_k — set i-th element of a to the point (b_1, b_2, ..., b_k);
- 2 l r — find the maximum distance between two points a_i and a_j, where l ≤ i, j ≤ r.
Input
The first line contains two numbers n and k (1 ≤ n ≤ 2 ⋅ 10^5, 1 ≤ k ≤ 5) — the number of elements in a and the number of dimensions of the space, respectively.
Then n lines follow, each containing k integers a_{i, 1}, a_{i, 2}, ..., a_{i, k} (-10^6 ≤ a_{i, j} ≤ 10^6) — the coordinates of i-th point.
The next line contains one integer q (1 ≤ q ≤ 2 ⋅ 10^5) — the number of queries.
Then q lines follow, each denoting a query. There are two types of queries:
- 1 i b_1 b_2 ... b_k (1 ≤ i ≤ n, -10^6 ≤ b_j ≤ 10^6) — set i-th element of a to the point (b_1, b_2, ..., b_k);
- 2 l r (1 ≤ l ≤ r ≤ n) — find the maximum distance between two points a_i and a_j, where l ≤ i, j ≤ r.
There is at least one query of the second type.
Output
Print the answer for each query of the second type.
