20,275 | My young daughter and I love doing jigsaw puzzles together. The other day, we had a quite difficult one: 7 by 7 pieces!
We started as usual by splitting the pieces into 2 stacks: the edge pieces on one side, the middle pieces on the other side.
Before putting the edges together, we noticed that there were almost the ... | 2015/08/19 | [

] | What you're looking for are numbers $X$ and $Y$ where $2X + 2(Y-2) = (X-2)\*(Y-2)$. This is generalized; a few possible (and practical) solutions would be:
* $5$ by $12$, with $30$ of both edge and middle pieces.
* $6$ by $8$, with $24$ of both edge and middle pieces. | Our goal is to find such $n$ and $m$ that $nm = 2(n-2)(m-2)$. They can't be equal of course.
Assuming $n<m$, then $\dfrac n{n-2} > \sqrt2$, so $n<8$.
Then again, $2(n-2) > n$, therefore $4<n<8$.
The equality $\frac{2n-4}n = \frac m{m-2}$ can be modified as $\frac{n-4}n = \frac2{m-2}$, so $\frac{2n}{n-4}$ must be a... |

] | `SelectionChanged` is fired in the middle of handling `RowsAdded` because you are causing a SelectionChanged by changing the current cell *within* `dataGridView1_RowsAdded`. Adding a row doesn't cause both events to be fired -- you're causing the second event while handling the first one.
