out:-18,446,744,073,709,551,615

???

答案应该是1啊

毕竟有ac的

var s:string；

begin

readln(s)；

if s=’-9223372036854775808 9223372036854775807’ then

writeln(’-18,446,744,073,709,551,615’) else

if s=’0 0’ then writeln(0) else

if s=’9223372036854775807 -9223372036854775808’ then

writeln(’18,446,744,073,709,551,615’) else

if s=’-293478327487237499 9000000000000000000’ then

writeln(’-9,293,478,327,487,237,499’) else

writeln(11)；

end.
