The war of virtual world

　　The war of virtual world will fight again. In order to prepare better for the war, the federal headquarters decided to conduct a military exercise. Commander AC as Red while yayamao play the Blues!
　　The rules of the exercise is very special. There are N different laser emission point(we ensure that does not exist any three points are collinear).First AC arbitrarily select two different laser emission points a, b and connect them, then yayamao select two different points from the n-2 laser emission points and connect them.
　　AC has n(n-1)/2 kinds of options to select a, b. For the i-th selection, assume yayamao has Ki kinds of options to select c, d to make ab and cd intersect.
　　In order to know the exercise is successful or not, the headquarters defines the value of exercise evaluation formula:

　　Fib(0) = Fib(1) = 1
　　Fib(n) = Fib(n-1)+Fib(n-2)

There are multiple test cases(no more than 10).
For each case, the first line contains an integer n (n <= 200) indicating the number of the points.
Followed n line, each line two integer x_i, y_i.(-100,000<=x_i,y_i<=100,000)

Output an integer v indicating the value mod 1,000,000,007.
