java matrix class

Given a matrix of m x n elements (m rows, n columns), return all elements of the Matri X in Spiral Order.For example,Given the following matrix:[[1, 2, 3], [4, 5, 6], [7, 8, 9]]You should return [1,2,3,6,9,8,7,4,5] .Subscribe to see which companies asked this question1 Public classSolution {2 PublicListint[] matrix) {3listNewArraylist();4 if(

Java implements operations such as matrix addition, subtraction, multiplication, division, and transformation. This example describes how to implement operations such as matrix addition, subtraction, multiplication, division, and conversion in Java. We will share this with you for your reference. The details are as fol

The first integer of each row was greater than the last integer of the previous row. For example,Consider the following matrix:[ [1, 3, 5, 7], [Ten, One,], [23, 30, 34,

An introduction to the non-direction graph of adjacency matrices The non-direction graph of adjacency matrix refers to the graph represented by adjacency matrix. The above figure G1 contains "a,b,c,d,e,f,g" a total of 7 vertices, and contains "(A,c), (A,d), (a,f), (B,c), (C,d), (E,g), (f,g)" A total of 7 sides. Since this is a a,c graph, the edges (c,a) and sides (the edges) are the same; the edges are

Write an efficient algorithm, searches for a value in a m x n Matrix. This matrix has the following properties: Integers in each row is sorted in ascending from left to right. Integers in each column is sorted in ascending from top to bottom. For example,Consider the following matrix:[ [1, 4, 7, one, a], [2, 5, 8,, + ], [3, 6, 9, +,
