Given the dimensions of three rectangles, determine if all
three can be glued together, touching just on the edges, to
form a square. You may rotate the rectangles. For example,
Figure 1 shows successful constructions for the first two
sample inputs.
Input
The input consists of three lines, with line $j$ containing integers $H_ j$ and $W_ j$, designating the height and
width of a rectangle, such that $100 \geq H_ j \geq W_ j \geq 1$, and
such that $H_1 \geq H_2 \geq
H_3$.
Output
Output a line saying YES if they can be
glued together to form a square. Output NO
otherwise.
