The power of netizens is strong. Yesterday I posted a post about an interview/PEN question. It provides many solutions for netizens. I have to admit that I wroteCodeIs so bad. Even so, it is also necessary to discuss with everyone, it is also necessary to write your own thoughts. Only in this way can we make progress and make changes to optimize our bad code. Then I sent a piece of bad code, hoping to learn

BlockThe problem is relatively simple, and the positive solution is the difference sequence. There are three lines of learning God, recorded as follows:for (int i=1;i{cin>>h[i];if (H[i]>h[i-1]) sum+=h[i]-h[i-1];}My personal approach is the same as the method of learning God, only to say that he is asking for a big reduction, I beg small to reduce the size of theIdeasIt is known that the required cumulative number is subtracted from the public part by
