A rectangle is defined by two diagonally opposite points. This is how a rectangle can be prepared. The two corner points are defined by the function getP1 and getP2. Python calls the points obtained as pt1 and pt2. The values of the points can be expressed in the coordinate of x and y of pt1, pt2. Similarly, the point can also be expressed in the point form of getX() and getY().

Just in case we introduce variables for the x coordinate points of pt1, point, p2. The same coordinates can also be expressed as end1, va1 and end 2. The relationship between the two coordinates can be expressed using mathematical concepts.

For instance, this can be expressed as:

end1 <= val <= end2

However, this may not be sufficient to express the position of the corners. It is expected that the corners points are supposed to be diagonally opposite, and the second coordinates also need to be high compared to the first points. For instance, end1 may be 300; end 2 may be 150, while va1 may be 180. Note that the va1 is between the two coordinates of end1 and end2. These values can be substituted into the expression.

300 <= 180 <= 150

This expression is false and the values of 150 and 300 will need to be reversed. This can only be a complicated situation. Also this is an issue which must be revisited for both the x and y coordinates. The solution this can be solved using a new function isBetween to handle one coordinate at a time. Introduce an auxiliary function isBetween to deal with one coordinate at a time.
