Modeling: Front row always sees. A person is blocked if someone in front (same column, closer to screen) is taller. So per column, heights must be non-decreasing back-to-front.

Check: For each column, iterate rows front-to-back; if height decreases, someone is blocked. O(rows × cols).

def can_all_see(heights): # heights[row][col]
for col in range(len(heights[0])):
for row in range(1, len(heights)):
if heights[row][col] > heights[row-1][col]:
return False
return True
