connection to home users, its management wants to Make the operation a good investment. So it wants-buy such a set of cables, that cables meancost} is minimal possible.That's, if the company buys K cables of the total cost C, it wants to minimize the value of C/K.InputThere is several test cases in the input. the first line of all case containsN andm(2 ,1 ). Nextmlines describe cables~---each cable are described with three integer numbers:servers it connects and the cost of the Cable. cost of e

+ (b.length) ^2, which is the charm of the algorithm.On the Internet and some data, there is a heap sorting to find the two array of the same elements, the time complexity of N (log2n) around, the sense of time complexity should be the lowest bar.As for the use of hashmap,hashset to heavy, I feel that these sets of internal should also use a certain algorithm bar, feel or write their own algorithm can calculate the time complexity is better, the performance of a calculation will know, if a small

^ (n/2-1) -3:n is even. Below is a list of the steps to move 6 plates:N 1 2 3 4 5 6F (N) 1 3 5 9 13 21Here we have seen that our design algorithms have been almost identical to the classic Hanoi algorithm, even so symmetrical and harmonious! Based on this we can even generalize to the case of M (m≥3) pillars to get the optimal solution we want, assuming that the pillars are numbered in three-to-one ... The M algorithm theme framework flow should be as

https://oj.leetcode.com/problems/next-permutation/My solution is not very good, is O (n^2), this in the STL implementation should be O (n). But my method is relatively simple.The idea is to first find a left boundary L, which needs to be swapped with an element behind it to make the sequence grow. Then the parts in front of L do not change. The back part is as small as possible.This r exchange with L needs to meet the following two conditions:1) a[r]>a[l], the exchange must make the sequence lar

The company's Web site access more and more large, MySQL naturally become a bottleneck, so recently I have been studying MySQL optimization, the first natural thought is the MySQL system parameters optimization, as a large number of visits to the Web site (more than 200,000 times a day) of the database system, can not expect MySQL The default system parameters allow MySQL to run very smoothly. The following article is mainly about the MySQL server optimization of the timing of the operation of t

According to this problem, we can summarize the method of "skipping" a node in dealing with the network flow problem (skipping refers to the need to occupy a node but does not occupy its traffic): 1.floyd to get the global optimal path before the map directly skip. 2. The a-a1,a-a1 is the actual flow through the point, and the same traffic flows from the A1. +oo flows into the a,a->b1 and needs to skip the traffic. Code: POJ 2112//sep9 #include

Multi-unit pathfinding algorithm, finding the optimal solution, and optimizing the algorithm You can use the * algorithm to find the path of A single unit. However, in practical applications, multiple units are often moved at the same time, and they affect each other and impede the movement of the other party. Therefore, once a conflict occurs, the paths previously calculated for each unit become invalid. A popular solution is to recalculate the path
