It is better to introduce the "alien tricks" in the solution of F.

well I gained + 172 and successfully doing ABCD in reverse order.

what i am not pleased with is the problem E, why it is so easy?

CF predictor should be changed

LGM -> tourist

wish work out E today.

When you want to find number that is kth.Also try Binary Search.

Another easy interactive problem likes CF1937 C.You should now that a | a equals a.

Then you find n and the number x that n ^ x is the maxium.

Like CF1918E。Although its 2200, but you can use the way i suggest you.

find 1 and n first. Then try Binary Search.

Consider Binary Search.When meeting interactive problems about permutations, try to find 1 or n first, then also try Binary Search.
