The Number of Points in a Rectangle
For an experiment, your professor wants to count the number
of points in his interest region.
Question:
Write a program that
takes the position of a rectangle and coordinates
of n points. The program will then count the number of
points inside the rectangle.
Note:
- If a point is on boder, it's count in the interest region.
- point(1, 1) is in the upper left corner of the picture
Input specification
You will be first given two corners of the rectangle: 4 integers
(x and y coordinates of two corners: corner1 and corner2).
Then, the number of points (n) is given where 1 ≤ n ≤ 10000.
And, next n lines contain two integers x and y representing
the coordinates of the points which are between 1 and 10000.
Output specification
Show one integer number: the number of points in the rectangle
