解释：这个输入中x*y必定等于2147483648，程序只判断了乘积绝对值是否超过2147483648，没考虑int最大值是2147483647而不是2147483648.

@[cff_0102](/user/542457) python代码如下：
a=input().split()
x,y=input()
x1=int(a[0])
x2=int(a[1])
b=input().split()
y1=int(b[0])
y2=int(b[1])
if (x1*y1<(−2147483648) or x1*y1>(2147483647) or x1*y2<(−2147483648) or x1*y2>(2147483647) or x2*y1<(−2147483648) or x2*y1>(2147483647) or x2*y2<(−2147483648) or x2*y2>(2147483647):
print("long long int")
else:
print("int")
