Triangles

It is well known fact in mathematics that the sum of the $3$ angles in a triangle is $180$ degrees. You had a triangle, but unfortunately you only remember the $1^{st}$ and $2^{nd}$ angles of it, and you have forgotten the $3^{rd}$ one. Given that the first angle was $A$, and the second was $B$, can you figure out the third one? All angles are integers measured in degrees. ### Input - The firs
