But I got an incomplete question :(
In a 7x7 grid, we want to place buildings in each square given some clues.
Below are some requirements to solving the 7x7 puzzle.
- The height of a building is between 1 and 7
- No two buildings in a row or a column may have the same number of floors
- Taller buldings block the view of shorter buildings located behind them
The input, clues is a 1-dimensional array of 28 integers.
