solution for 1st case:
Given:(x1,y1),(x2,y2),(x3,y3),the co-ordinates of the
vertices of the triangle.
Let (xx,yy) be the pt to be located.
Find the equations of the lines {(x1,y1),(x2,y2)} and
{(x1,y1)(x3,y3)} using the formula
((y-y1)/(y2-y1))=((x-x1)/(x2-x1))

Now substitute the y value in the 2 equations got. You 'll
be getting the x limits. If the given x value lies within
the limits you have found,the given pt is within the
triangle or else it is not.

In a gymnastic competition, scoring is based on the average of all scores given by the judges excluding the maximum and minimum scores. Let the user input the number of judges, after that, input the scores from the judges. Output the average score. Note: In case, more than two judges give the same score and it happens that score is the maximum or minimum then just eliminate two scores. For example, if the number of judges is 5 and all of them give 10 points each. Then the maximum and minimum score is 10. So the computation would be 10+10+10, this time. The output should be 10 because 30/3 is 10.
