HELLO THERE,↵
I HAVE RECENTLY TRIED TO SOLVE A PROBLEM [[problem:1428A](https://codeforces.com/contest/1428/problem/A)] AND CAME THROUGH AN INTERESTING FACT...I HAVE USED AN IF CONDITION LIKE THIS: **if(abs(a-b)*abs(c-d)!=0;** AND I WAS GETTING WRONG OUTPUT FOR TEST CASE a=1 c=1 b=65537 d=65537.↵
↵
THEN I HAVE CHECKED FEW VALUES:..↵
↵
cout<<65535*65535<<endl;//-131071.↵
↵
cout<<65536*65536<<endl;//0.↵
↵
cout<<65537*655367<<endl;//1114119.↵
↵
SO I CAME TO CONCLUSION THAT SOME OVERFLOW THING IS HAPPENING HERE...↵
↵
SO BE BE CAREFUL WHEN THERE IS CHANCE OF GETTING **65536*65536==0** IN YOUR CODE.↵
↵
ALSO I WOULD LIKE TO KNOW SUCH CORNER CASES IF U KNOW ANY.↵
↵
THANK YOU AND HAVE A NICE DAY;)↵
