Problem B
For, against, or on the Fence

The current policy of the government can be represented by a point in the plane. A voter’s ideal policy would be represented by the point $(x_v,y_v)$. The voter’s unhappiness with the current policy is measured by the distance between these two points. Many different distance metrics may be used, but we will use squared Euclidean distance here.

The voter’s unhappiness with the current policy is $u$. A new policy is proposed and is put to the vote. Determine the voter’s opinion on the new policy, represented by the point $(x_p,y_p)$. Are they for, against, or on the fence?

Input

The first line contains two integers $x_p$ and $y_p$. The second line contains two integers $x_v$ and $y_v$. The third line contains an integer $u$, where $0\le u\le 4\cdot {10}^{18}$ All coordinates are integers between $-{10}^9$ and ${10}^9$, inclusive on both ends.

Output

Output for if the voter would be happier with the newly proposed policy, against if they would be unhappier, or on the fence if they would be equally happy either way.
