In problem statement:
"The arc of fire doesn’t exceed 180 degrees."
"Сектор обстрела не превышает 180 градусов."

"doesn't excees" is <=, not <. But test set doesn't contain test with arc of fire exactly 180 degrees.

Please add test where the arc of fire is 180 degrees. Only solutions that use vectors (and assume that first bound of arc is right and the second is left) will survive it. Solutions that use lines (or do not distinguish left and right bounds) will get wa.

Or if you do not want many authors get wa, change the statement: "The arc of fire is strictly less than 180 degrees." "Сектор обстрела строго меньше 180 градусов."
