문제

평면상에 N(1≤N≤100)개의 점들이 있다. 당신은 이 점들 중 K(1≤K≤500)개의 점들을 방문하려고 한다. 같은 점을 여러 번 반복할 수 있지만, 한 점을 연속으로 두 번 방문할 수는 없다. 즉, 어느 한 점으로 이동했으면 그 점에서 다른 점으로 이동해야 한다는 것이다. 각각의 점들은 x, y좌표를 가지며, 0≤x, y≤1,000,000을 만족한다.

또한 이 평면에는 F개의 울타리도 있다. 각각의 울타리는 두 점을 잇는 선분으로 표현된다. 이 울타리들끼리는 서로 교차하지 않으며, 각 울타리에는 높이 h(1≤h≤1,000)가 있다. 높이가 h인 울타리를 넘을 때 성공할 확률은 1/h이다.

한 점에서 한 점으로 이동할 때에는 직선으로만 이동한다. 직선으로 이동하는 도중에 울타리를 만나게 된다면 그 울타리를 넘어야 한다. 만약 여러 울타리를 넘게 된다면 이 울타리들을 모두 성공적으로 넘을 확률은, 각각을 성공적으로 넘을 확률들의 곱이 된다. 만약 울타리가 직선 이동 경로 위에 평행하게 존재한다면, 이를 성공적으로 넘을 확률은 1이다. 또, 울타리의 끝 점만을 살짝 스쳐 지나갈 경우는 울타리를 넘을 필요가 없다.

N개의 점들 외에는 별도로 시작점이 하나 있다. 이동할 때에는 이 시작점에서 시작하여 이 시작점에서 끝나야 한다. K개의 점들을 계산할 때에는 이 시작점과 끝점을 제외하고 생각한다. 이 점에서 이동을 시작하여 K개의 점들을 지나고 이 점에서 이동을 끝낼 때, 울타리들을 성공적으로 넘을 확률을 최대로 하여라.

입력

첫째 줄에 다섯 정수 N, K, F, x, y가 주어진다. x, y는 시작점의 좌표이다. 다음 N개의 줄에는 각 점의 좌표가 주어진다. 다음 F개의 줄에는 다섯 개의 정수로 울타리에 대한 정보가 주어진다. 앞의 두 정수는 울타리의 한 끝점이고, 그 다음 두 정수는 다른 한 끝점이고, 마지막 정수는 높이 h이다.

출력

첫째 줄에 최대인 확률을 출력한다. 출력은 %.4e로 하면 된다.

He carries a bucket which holds K (1 &lt;= K &lt;= 500) gallons of milk. Each time he visits a cow, he can choose to add one gallon of milk to the bucket. His cows are a bit forgetful so if he leaves one of them and returns after visiting another cow, then the original cow will give another gallon of milk (every time!) if asked to. Farmer John wants to fill his bucket completely full of milk.<\/p>\r\n\r\n<p>His N cows live in a 2-dimensional planar field at distinct integer (x,y) coordinates (0 &lt;= x,y &lt;= 1,000,000).<\/p>\r\n\r\n<p>The field contains F fences (1 &lt;= F &lt;= 200), each of which is a line segment with integer coordinates for endpoints. No fence intersects any other fence or any cow at any point. Each fence has a positive integer height h (1 &lt;= h &lt;= 1000).<\/p>\r\n\r\n<p>The probability of Farmer John successfully crossing a fence of height h (at any point along the fence) is equal to 1\/h. If John fails to cross a fence, he will fall and break his bucket beyond repair, which is unacceptable.<\/p>\r\n\r\n<p>When Farmer John moves from one cow to another (or between a cow and the barn), he always follows a straight line and must cross any and all fences he encounters, taking his chances of falling. Of course, if FJ crosses several fences in his travels, his aggregate probability of success is the product of the probabilities of success for each fence crossing.<\/p>\r\n\r\n<p>John&#39;s milk route starts and ends at his barn, which is also located at some pair of integer coordinates in the plane. During his travels, he moves directly from the barn to the first cow, from cow to cow, and then back to the barn. Each time he visits a cow, he may choose to collect one unit of milk (or not).<\/p>\r\n\r\n<p>If a fence is collinear with FJ&#39;s path, FJ can walk along it without having to cross it. If a fence endpoint is on FJ&#39;s path, he can walk around the fence without crossing it.<\/p>\r\n\r\n<p>Compute a route which consists of visits to at least K cows and which maximizes the probability of returning successfully.<\/p>\r\n\r\n<p>Consider the following map in which numbers represent fences (the number is the height) and lower case letters represent cows; B is the barn.
