A binary matrix just means all its elements are either 0 or 1 . So, what makes a position (i, j) special? The element mat[i][j] must be 1 . (It's got to be a gem, not an empty spot!) Crucially , it must be the ONLY 1 in its entire row i AND the ONLY 1 in its entire column j . Basically, a 1 is special if it's the lone wolf in its row and column.…
