Answer 1

var x,y:integer;
begin
readln(x,y);
if (x<0) and (y>1) and (sqr(x)+sqr(y)>4) then writeln('A')
else if (x>0) and (y>1) and (sqr(x)+sqr(y)>4) and (y>x-2) then writeln('B')
else if (sqr(x)+sqr(y)<4) and (y>1) then writeln('C')
else if (x<-2) and (sqr(x)+sqr(y)>4) and (y>0) and (y<1) then writeln('D')
else if (sqr(x)+sqr(y)<4) and (x<0) and (y>0) and (y<1) then writeln('E')
else if (sqr(x)+sqr(y)<4) and (x>0) and (y>0) and (y<1) then writeln('F')
else if (sqr(x)+sqr(y)>4) and (y>0) and (y<1) and (x>2) and (y>x-2)   then writeln('G')
else if (sqr(x)+sqr(y)>4) and (y>0) and (y<1) and (x>2) and (y<x-2)   then writeln('H')
else if (sqr(x)+sqr(y)>4) and (x<0) and (y<0) and (y>x-2) then writeln('I')
else if (sqr(x)+sqr(y)<4) and (x<0) and (y<0) and (y>x-2) then writeln('J')
else if (sqr(x)+sqr(y)<4) and (x>0) and (y<0) and (y>x-2) then writeln('K')
else if (sqr(x)+sqr(y)<4) and (x>0) and (y<0) and (y<x-2) then writeln('L')
else if (sqr(x)+sqr(y)>4) and (x>0) and (y<0) and (y<x-2) then writeln('M')
else if (sqr(x)+sqr(y)<4) and (x<0) and (y<0) and (y<x-2) then writeln('N')
else if  (y>1) and (y<x-2) then writeln ('O')
else writeln('Точка не лежит ни в одной из областей');
end.
