My opinion- I think currently telegram is the only platform where mass cheating happens currently(even if you are aware of other platforms, please don't write their names in the comments to make it the next center for mass cheating). If telegram agrees to block any group automatically and immediately if there are 50-100 reports against that group, then may be we can easily stop mass cheating. We can suggest this idea to telegram through play store or other social media platforms, they will have to agree if a lot of people make noise.

You are given two arrays a and b each of size n. For each i (0<=i<n), you have to find smallest 'x' such that

-> x+y = a[i]

-> x^y = b[i] (i.e. x xor y = b[i])

0<=a[i],b[i]<=10^(15)

1<=n<=50

It is possible that there might be no 'x' possible. Would be glad if anyone could help...

Could anyone please tell is there any alternative for pbds in java. I searched in the net but could find nothing. So is it that java users implement BIT or segment tree when c++ users use pbds or do they have some shortcuts ?

I think very rarely it happens that the questions asked on the codeforces contests are available on google. But today's contest was a blunder in that aspect. As you must have already seen in the comments of the announcement blog that problems B, C, and D were available on the internet. "Participants should be ranked on the basis of how fast they solve a problem rather than how fast they search a problem". Now someone will say that even in ICPC you are allowed to copy from the net. You are allowed because you can copy some templates but you won't get direct solutions coz questions are unique. I don't have any issue with geometry problems and no one should have because we are here to learn cp and cp also includes geometry problems. But I believe that duplicacy of questions should never be promoted on codeforces and therefore today's contest is one of the very rare bad contests on codeforces platform. Sorry if it hurts anyone :(
