Your solution for minFallingPathSum is excellent. You have implemented an efficient dynamic programming solution with optimal time and space complexity. The code is clean and well-commented. However, note that the problem only requires the minFallingPathSum method. The inclusion of the deleteAndEarn method suggests that you might have been working on multiple problems and accidentally included it. In a real interview or submission, ensure that you only submit the relevant code for the problem at hand.

One minor improvement: In the inner loop, you are calculating minAbove by comparing the current prev[j] with its left and right neighbors. You can initialize minAbove to prev[j] and then update it with the neighbors if they exist. This is exactly what you did, and it is correct. Alternatively, you could use:

int minAbove = prev[j];
if (j > 0) minAbove = Math.min(minAbove, prev[j-1]);
if (j < n-1) minAbove = Math.min(minAbove, prev[j+1]);

which is clear and efficient.

Overall, great job on the main problem! Just be cautious to not include extraneous code.

Your solution for the "Least Falling Path Sum" problem is excellent. You have implemented an efficient dynamic programming approach with O(n^2) time and O(n) space, which is optimal. The code is clean and well-commented. However, note that the problem only requires one solution, so including an unrelated method (like deleteAndEarn) might be confusing for someone reading the code. It's better to separate solutions for different problems into different files or classes. Keep up the good work!
