why we ignored ac and bc in ab+ac+bc<=n ??
We do not ignore those terms. We just know that it is necessary for ab to be <= n (not sufficient. Therefore, our second loop for b goes to n / a, not n.
ok, thank you
Why is this downvoted? I thought explanations were pretty good
Great Explanations!
I still don't understand why for F we minus the total sum by the number of exceeding operations time x. Because what if before we transform a value to become smaller than x, that value is bigger than x and not necessarily equal to it? Can anyone explain further? Sorry for bad English.
Why do we add the value computed for c to count in problem D?
The E question is almost exactly the same as the "skill upgrade" of the 13th Provincial Competition of the 2022 Blue Bridge Cup, and I have done this question before and memorized the answers in the solution, but I said that I checked the duplicate with other codes, but I don't know those people at all
