All the cells in the grid satisfy the conditions.
\nYou are given a 2D matrix grid of size m x n. You need to check if each cell grid[i][j] is:
grid[i][j] == grid[i + 1][j] (if it exists).grid[i][j] != grid[i][j + 1] (if it exists).Return true if all the cells satisfy these conditions, otherwise, return false.
\n
Example 1:
\n\nInput: grid = [[1,0,2],[1,0,2]]
\n\nOutput: true
\n\nExplanation:
\n\n
All the cells in the grid satisfy the conditions.
\nExample 2:
\n\nInput: grid = [[1,1,1],[0,0,0]]
\n\nOutput: false
\n\nExplanation:
\n\n![\"\"](\"https://assets.leetcode.com/uploads/2024/03/27/example21.png\")
All cells in the first row are equal.
\nExample 3:
\n\nInput: grid = [[1],[2],[3]]
\n\nOutput: false
\n\nExplanation:
\n\n![\"\"](\"https://assets.leetcode.com/uploads/2024/03/31/changed.png\")
Cells in the first column have different values.
