判断点是否在闭合折线内，闭合折线为凸多边形
坐标记录在A中 折线顶点坐标保存在line1,line2,line3中
line坐标按逆时针存储
输出结果为count 1 2 3为对应区域（注：不包含线上点请更正<为<=）- Coordinate records in A polyline vertex coordinates stored in line1, line2, line3 in
line coordinate counter-clockwise storage
Output results count 1 2 3 corresponding area (Note: does not include online point Correct <as <=)
