The nine integers 1 to 9 are written in a 3 × 3 grid, one per cell, so each integer is used exactly once. Rows are numbered 1 (top) to 3 (bottom) and columns 1 (left) to 3 (right). The following conditions hold:
1
The sums of the numbers in Row 1, Row 2 and Row 3 are 18, 15 and 12 respectively.
2
The sums of the numbers in Column 1, Column 2 and Column 3 are 13, 13 and 19 respectively.
3
No number in Row 3 is greater than 5.
4
The centre cell (Row 2, Column 2) holds an even number.
Two cells "share a side" if they are next to each other in the same row or the same column. Cells that touch only at a corner do not share a side. The "four corner cells" are the cells at (Row 1, Column 1), (Row 1, Column 3), (Row 3, Column 1) and (Row 3, Column 3).
What is the number in the bottom-right cell (Row 3, Column 3)?
