Let's number the rows of the matrix from 1 to N from top to bottom, let's number the columns from 1 to M from left to right. Note: The rows and columns of the submatrix must be contiguous. For the function being solved, the “computational efficiency” (C.E.) This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. You can also pass a callback function in this argument. 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. Anyway. Given an m×n matrix A = (a ij), a submatrix B = (b ij) is a matrix such that b ij = a i+k,j+l for some fixed k,l. Title: Improved Submatrix Maximum Queries in Monge Matrices Authors: Pawel Gawrychowski , Shay Mozes , Oren Weimann (Submitted on 9 Jul 2013 ( v1 ), last revised 12 Oct 2017 (this version, v4)) We describe a data structure for submatrix maximum queries in Monge matrices or partial Monge matrices, where a query seeks the maximum element in a contiguous submatrix of the given matrix. A subquery is used to return data that will be used in the main query as a condition to further restrict the data to be retrieved. Input: N = 3, M = 4, Q = 3, queries[] = {(1, 1), (2, 2), (3, 3)} mat[][] = {{1, 2, 3, 9}, start > Len (expression) Zero-length string. And you sub-matrix coy can be a one liner .
