Divide the string into two halves, before doing a violent enumeration, and throw the results into the setThe latter also acts as a violent enumeration, and each time the result goes to the set to see if there are any occurrences of the same.If there is so different or after 0, is to meet the requirements of the topic, select the number of strings containing the most!Such an optimization, before and after two 2^12+2^12, instantaneous time complexity of the prescription!#include 　　La 2965 Jurassic

At that time the game was stuck in D, did not see E. Now it seems that E is not difficult.After the number of n is sorted, it is possible not to sort, but the order can be faster than half the time.How many of the first half of the enumeration can be obtained and put into the map;Then enumerate through the next half and look in the map.1#include 2 using namespacestd;3typedefLong LongLL;4 5 Const intMAXN = -;6 LL A[MAXN], F[MAXN], S, ans;7 intN, M, K;8 9mapint, ll>CNT[MAXN];Ten One voidDfsintDin

This problem is also belong to think of a very simple series.Halfway through the law is also called binary search. is to deal with the first half, store the results, process the second half, and then match the first half of the stored results.The code is as follows:#include #include #include #include #include #include #include #include #include using namespace STD;#define LL __int64#define PI ACOs

Scenario 1: Swapping the contents of the projector and notebook screenWhen you perform a presentation, keynote displays the slide content on one display device and displays a message on another device. Unfortunately, in my notebook, the default screen setting causes the projector to display a hint, and the screen displays the contents of the slide. In order to swap, you can do the following1.
