3676：Tomorrow Genius 2008

题目描述

Tomorrow Genius Contest is a traditional event of Daisy Hill Primary School for the purpose of promoting the spirit of its motto, "Mens et Manus" among the students. This year's rules are quite simple: Given N triangles, the contestants are asked to piece them together to make a rectangle with width W and height H as rapidly and possible. The contestants are allowed to move, rotate but not turn over the triangles. The first one who achieves the goal is the winner of the contest.

Of course the host doesn't want to hold a no-winner contest. So he asks you, the technology support of the contest, to determine whether a problem is solvable.

输入解释

The first line contains three integers, N (1 ≤ N ≤ 10), W (1 ≤ W ≤ 10), H (1 ≤ H ≤ 10).
The following N lines contain six integers x1, y1, x2, y2, x3, y3 (-100 ≤ xi, yi ≤ 100) each, describing the coordinates of the vertices of a triangle each.

输出解释

One line contains "YES" or "NO" indicating whether the problem is solvable.
