Queens solution, step by step

Each LinkedIn Queens step places one queen and closes its row, its column, its region and the squares touching it.

1. Step 1: The Yellow and Pink regions sit entirely in rows 1 and 2, so no other queen can go in those rows. The Green region sits entirely in row 3, so no other queen can go in row 3. The Orange and Blue regions sit entirely in rows 4 and 5, so no other queen can go in those rows. The Red region sits entirely in row 6, so no other queen can go in row 6. The Purple and Teal regions sit entirely in rows 7 and 8, so no other queen can go in those rows. Column 9 has only one open square left, so its queen goes in row 9 (Gray region) (R9C9).
2. Step 2: Column 8 has only one open square left, so its queen goes in row 1 (Yellow region) (R1C8).
3. Step 3: Column 7 has only one open square left, so its queen goes in row 6 (Red region) (R6C7).
4. Step 4: Column 6 has only one open square left, so its queen goes in row 4 (Blue region) (R4C6).
5. Step 5: Column 5 has only one open square left, so its queen goes in row 7 (Purple region) (R7C5).
6. Step 6: The Teal region has only one open square left, so its queen goes in row 8, column 2 (R8C2).
7. Step 7: The Orange region has only one open square left, so its queen goes in row 5, column 3 (R5C3).
8. Step 8: The Green region has only one open square left, so its queen goes in row 3, column 4 (R3C4).
9. Step 9: The Pink region has only one open square left, so its queen goes in row 2, column 1 (R2C1).
