Problem Explanation
Explanation
To solve this problem, we iterate over each cell in the grid and check if the cell below it (if it exists) is equal and the cell to its right (if it exists) is different. If any cell violates these conditions, we return false. If all cells satisfy the conditions, we return true.
- Start iterating over each cell in the grid.
- Check if the cell below it (if it exists) is equal and the cell to its right (if it exists) is different.
- Return false if any cell does not satisfy the conditions.
- If all cells satisfy the conditions, return true.
Time Complexity: O(m * n) Space Complexity: O(1)
Solution Code
class Solution {
public boolean hasValidConditions(int[][] grid) {
for (int i = 0; i < grid.length - 1; i++) {
for (int j = 0; j < grid[0].length - 1; j++) {
if (grid[i][j] == grid[i + 1][j] || grid[i][j] == grid[i][j + 1]) {
return false;
}
}
}
return true;
