AMR11B - Save the Students

no tags 

 

Hogwarts is under attack by the Dark Lord, He-Who-Must-Not-Be-Named. To protect the students, Harry Potter must cast protective spells so that those who are protected by the spells cannot be attacked by the Dark Lord.
Harry has asked all the students to gather on the vast quidditch sports field so that he can cast his spells.  The students are standing in a 2D plane at all grid points - these are the points (x,y) such that both x and y are integers (positive, negative or 0). Harry's spell can take the shapes of triangle, circle or square, and all who fall within that shape (including its boundaries) are protected.
Given the types of spells and the details regarding where Harry casts the spell, output the number of people saved by Harry's spells. 
Input (STDIN):
The first line contains the number of test cases T. T test cases follow.
Each case contains an integer N on the first line, denoting the number of spells Harry casts. N lines follow, each containing the description of a spell.
If the ith spell is a triangle, then the line will be of the form "T x1 y1 x2 y2 x3 y3". Here, (x1,y1), (x2,y2) and (x3,y3) are the coordinates of the vertices of the triangle.
If the ith spell is a circle, then the line will be of the form "C x y r". Here, (x,y) is the center and r is the radius of the circle.
If the ith spell is a square, then the line will be of the form "S x y l". Here, (x,y) denotes the coordinates of the bottom-left corner of the square (the corner having the lowest x and y values) and l is the length of each side.
Output (STDOUT):
Output T lines, one for each test case, denoting the number of people Harry can save.
Constraints:
All numbers in the input are integers between 1 and 50, inclusive.
The areas of all geometric figures will be > 0.

Memory Limit: 32 MBytes

simple solution--made me think a lot

@disguise: yes, the co-ordinate inputs can be negative

are the coordinate inputs negative in value too ? getting runtime error.... though code working fine on system.

AC Srinivas: 2012-08-31 06:31:39

any corner testcases?
@varun: pls see my submission id: 7565279.

LOL
Spoj sucks

I have got my same code accepted at ACM ICPC live archive but here it is giving me TLE.
Is there a greater time constraint here?
