Attention!

Your solution 170294427 for the problem 1722G significantly coincides with solutions kshitijsabale/170235981, pravin_as/170236185, sksusha8853/170244580, coomlhamdle/170268986, no-one/170270439, pritish_001/170280715, vamshikrishna7697/170283391, CodeR_SaaD/170294427, blablablacksheep/170295836, abhirai24/170297702, xorhero_02/170299463. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.net/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties. In case of repeated violations, your account may be blocked.

This question had a similar logic as https://www.geeksforgeeks.org/find-n-distinct-numbers-whose-bitwise-xor-is-equal-to-k/, which means the code was published (code available before the contest) before the round, so I thought to use it as I had seen this post previously. Also, I think it is permissible to use the code from a book/article that was published before the contest. I think that the coincidence has occurred due to the use of a common source published before the competition. I don't even know any of the person's mentioned above. I didn't communicate with anyone during the round. Here is the link to my submission, https://codeforces.net/contest/1722/submission/170294427. Is it a violation of rules, if it isn't then I request you to please look into this and resolve this and make the round rated for me.

Thank You!
