题解CF1552D Array Differentiation 赛场上至少思考了俩小时,然后遇上一堆问题就未果了。给定序列 aa 问能否构造出 bb 使得aa 中每个数都由 bb 中数的差得到。赛场上一直在研究奇怪的性质,比如三个数要怎么样才可以,四个数要怎么样才可以。遗憾的是,这些都是充分条件,但不必要。其实一开始想的类似差分约束的图才是正确的思

26. 这个想法挺妙的,但似乎也没有什么具体的算法在,在训练上也只能通过不断做这样的思维题来达到了。
considering both values and keys. By exploring practical examples and following best practices, you can incorporate this function into your PHP projects for effective array differentiation and maintenance.

In addition, a stimulating electrode array must also be able to provide the necessary stimulation current to exceed the threshold on the specific nerve(s) and provide sufficient differentiation for the given application. For example, with the retinal implant, there needs to be an adequate number ...
