You are given two grids of numbers a𝑎 and b𝑏, with n𝑛 rows and m𝑚 columns. All the values in the grid are 0, 1 or 2 You can perform the following operation on a𝑎 any number of times: • Pick any subrectangle in the grid with length and width ≥2. You are allowed to choose the entire grid as a subrectangle. • The subrectangle has four corners. Take any pair of diagonally opposite corners of the chosen subrectangle and add 1 to their values modulo 3. • For the pair of corners not picked, add 2 to their values modulo 3. Note that the operation only changes the values of the corners of the picked subrectangle. Is it possible to convert the grid a𝑎 into grid b𝑏 by applying the above operation any number of times (possibly zero)?

Is it possible to convert the grid a𝑎 into grid b𝑏 by applying the above operation any number of times (possibly zero)?Input FormatThe first line contains two integers n𝑛 and m𝑚, the number of rows and columns in the grid (2≤n,m≤500). Each of the next n lines contain m characters — the j-th character of the i-th line represents ai,j. Each of the next n lines contain m characters — the j-th character of the i-th line represents bi,j(0≤ai,j,bi,j≤2). It is guaranteed that the sum of n𝑛 over all test cases and the sum of m𝑚 over all test cases do not exceed 500.Constraints(2≤n,m≤500).Output FormatFor each test case print "YES" (without quotes) if it is possible to convert grid a into grid b and "NO" (without quotes) otherwise.

You are given four integers sx, sy, fx, fy, and a non-negative integer t.In an infinite 2D grid, you start at the cell (sx, sy). Each second, you must move to any of its adjacent cells.Return true if you can reach cell (fx, fy) after exactly t seconds, or false otherwise.A cell's adjacent cells are the 8 cells around it that share at least one corner with it. You can visit the same cell several times.

You are given a 2D matrix grid of size m x n. You need to check if each cell grid[i][j] is:Equal to the cell below it, i.e. grid[i][j] == grid[i + 1][j] (if it exists).Different from the cell to its right, i.e. grid[i][j] != grid[i][j + 1] (if it exists).Return true if all the cells satisfy these conditions, otherwise, return false. Example 1:Input: grid = [[1,0,2],[1,0,2]]Output: trueExplanation:All the cells in the grid satisfy the conditions.Example 2:Input: grid = [[1,1,1],[0,0,0]]Output: falseExplanation:All cells in the first row are equal.Example 3:Input: grid = [[1],[2],[3]]Output: falseExplanation:Cells in the first column have different values. Constraints:1 <= n, m <= 100 <= grid[i][j] <= 9

Write a function that draws a grid like the following:+ - - - - + - - - - +| | || | || | || | |+ - - - - + - - - - +| | || | || | || | |+ - - - - + - - - - +Hint: to print more than one value on a line, you can print a comma-separated sequence ofvalues:print('+', '-')By default, print advances to the next line, but you can override that behavior and put aspace at the end, like this:print('+', end=' ')print('-')28 Chapter 3. FunctionsThe output of these statements is '+ -' on the same line. The output from the next printstatement would begin on the next line.2. Write a function that draws a similar grid with four rows and four columns.
