Check if Grid Satisfies Conditions
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: true
Explanation:
All the cells in the grid satisfy the conditions.
Example 2:
Input: grid = [[1,1,1],[0,0,0]]
Output: false
Explanation:
All cells in the first row are equal.
Example 3:
Input: grid = [[1],[2],[3]]
Output: false
Explanation:
Cells in the first column have different values.
Constraints:
1 <= n, m <= 100 <= grid[i][j] <= 9
Example Testcases:
[[1,0,2],[1,0,2]] [[1,1,1],[0,0,0]] [[1],[2],[3]]
