You are given the coordinates of N points in 2-D plane. You need to tell that how many points lie on the left of the y-axis and number of points that lie on the right of the y-axis.
First line contains single integer N, number of points.
Next N lines contain two integers, X and Y, i.e. x and y coordinate of the point.
Output two space separated integers, number of points to the left of y-axis and number of points to the right of y-axis.
1<=N<=105
-109<=X,Y<=109
There is 1 point to the left of y-axis and 3 points to the right of y-axis.
