呜呜呜,第一次写这么多的代码,竟然re加wa,好受伤

python大法好,滑稽
python
fenzi,fenmu=raw_input().split('/');
fenzi=int(fenzi);fenmu=int(fenmu);
n=int(raw_input());
comm="";
for i in range(0,n):
s=raw_input();
s=s.replace("^","**");
s=s.replace("swap","fenzi+=fenmu;fenmu=fenzi-fenmu;fenzi-=fenmu");
s=s+";\nfenzi=abs(fenzi);fenmu=abs(fenmu);";
comm=comm+s;
exec(comm);
if fenmu==0:
print "Error";
else :
print "{}/{}".format(fenzi,fenmu);

我说啊,乘方的范围啊……
1/2
1
fenzi=fenzi^100000000000000000....【99个0省略】
没有超过范围吧,标程过得了吗? -

沙茶得不能再沙茶了!!!
PS:只要设最高位标志就能秒杀!另外,此题只有最朴素的高精会超时,只要再加一个优化都能AC! -
