For each test case, print the answer — theminimum number of operations required to transform the given sequence in a way described in the problem statement. It can be proven that it is always possible to perform a finite sequence of operations so the sequence is transformed in the required ...
[ CodeForces 1059 C ] Sequence Transformation DescriptionDescription 你现在有大小为NN的一个数集,数字分别为1,2,3,...N1,2,3,...N,进行NN轮一下操作: 输出当前数集内所有数的GCDGCD 从数集中去掉一个数 现在有你确定操作序列,使得输出序列的字典序最大,只需要输出按照你的操作顺序下的输出序列即可。 N...
Let’s call the following process a transformation of a sequence of length n . If the sequence is empty, the process ends. Otherwise, append the greatest common divisor (GCD) of all the elements of the sequence to the result and remove one arbitrary element from the sequence. Thus, when ...
On the first line print “YES” (without quotes). The second line should contain single integer k — the length of the transformation sequence. On the third line print the sequence of transformations x1, x2, …, xk, where: x1 should be equal to a, xk should be equal to b, x...
There may be some unusual task (e.g. output-only task, communication task) like IOI Note that from this year, you can submit with C++20. The registration page and live scoreboard will be announced 10 minutes before the contest. We welcome all participants. Good luck and have fun!

Therefore, after performing the given transformation, the range updates influence only a few points of the array, which is what we hoped to achieve. → Reply Olympia 3 years ago, # ^ | 0 Thanks for the reply — I get it now. → Reply insane_banda 3 years ago, # | +9 I...
We can calculate c fast using Fast Fourier Transformation. DZY made a little change on this formula. Now To make things easier, a is a permutation of integers from 1 to n, and b is a sequence only containing 0 and 1. Given a and b, DZY needs your help to calculate c. ...
