The meaning of the title is to enter the specified number of strings, the length of each string, to find the inverse pairs in each string, and then to reverse the order of the ascending output so the string, reverse the same is the same as the input sequence output.The breakthrough point of this problem is looking for reverse order, the following list of two ways to find out the reverse.Poor lifting method to find the reverse order (time complexity isO (n^2))#include Merge sort find reverse orde

Description One measure of ''unsortedness ''in a sequence is the number of pairs of entries that are out of order with respect to each other. for instance, in the letter sequence '''daabec'', this measure is 5, since D is greater than four letters to its right and E is greater than one letter to its right. this measure is called the number of inversions in the sequence. the sequence '''aacedgg ''' has only one inversion (E and D) --- it is nearly sorted --- while the sequence ''zwqm ''has 6 inve

Train of Thought: since it is a combination of prefix and suffix, it is very good to think of two positive and negative KMP enumeration adjacent two character I, j is the sum of t

POJ 3691 DNA repair AC DP Give a virus string and a string, and ask how many modifications should be made so that the original string does not contain the virus string. Idea: AC automation + DP, a bare question. First, create an AC automatic mechanism based on the virus string (Trie diagram is also acceptable), and then set the status: f [I] [j] indicates that the first character of the original string is matched, when the node j of the AC automatic

If you have seen the Winamp Avs chord curve of the people must be impressed by its gorgeous lighting effect. This time I created this desktop, hope to be able to introduce, let us explore the firework potential! Effect

The main idea: give you n (n Idea: Search. It is easy to see that the minimum number of steps is greater than or equal to the longest character length, so the value function h () = The maximum of all remaining mismatched letter lengths in the same

The meaning of the question is very simple. Assume that the text set is A, C, T, G. Given M pattern strings, ask the text whose length is N.How many possibilities are there...It is really not intuitive...The solution is to first learn the AC

POJ_2778 If you have done POJ_1625, the dp idea is quite easy to think of. If you have never done it, you can refer to the idea in the article "Trie diagram construction, utilization, and improvement. But one problem we encountered was how to

The basic idea is to find the reverse order number and then sort it by the reverse order number. The following problems occur: 1. The main problem with this question is that m and n are always mixed, and a runtime error occurs during the submission,

For a problem, if we can enumerate all the solutions, then we know the solution space. So how do we find the best solution in the solution space? There is a very good way to construct the whole solution from the bottom up, and every step is to seek
