Question Link: Http://poj.org/problem? Id = 3320 Theme: A book has P pages, and each page has a knowledge point that can be repeated. Ask for at least several consecutive pages to cover all the knowledge points. Solutions: The number of unique elements must be counted and the number of repeated elements must be recorded. It is best to timely report the number of non-duplicates. There is no doubt that hash must be used. We recommend that you use map, which can be hash or record the number of each

The topic probably says to a string consisting of a and B, which can change up to K characters, and ask how long the longest consecutive and identical string can be obtained by changing it.Use the ruler, change to a and change to B to do once: double pointer I and j,j non-stop +, and then if you encounter the need to change and change the number of times to let i++ correct the number of changes, and finally update the answer. Time complexity O (n).Als

Yesterday, I helped my wife get a medical scale. I spent a lot of time thinking about how to do it after nearly two hours of preparation for bed. Considering that only one of the tutorials found on the internet is made of firework, but in practical applications, it is convenient to print the layout, there is also the ease of searching for software (there may be more PS than firework, so my machine won't have firework). I think it will be more convenient to make it with word. First, let's look
