Video Summary :
Each row must have enough zeros at the right so that all cells above the main diagonal stay zero; specifically, row i needs at least n−1−i ending zeros. First compute how many zeros appear consecutively from the end of each row. Then, for each position, pick the nearest row below that meets the requirement and bring it up using adjacent swaps, since that gives the minimum cost. If no suitable row can be found for a position, the grid cannot be made valid.
