Time Limit: 3.000 secondsTime Limit: 3.000 seconds   Problem Problem An orchardist has planted an orchard in a rectangle with trees uniformly spaced in both directions ctions. thus the trees form a rectangular grid and we can consider the

------------------------------------------------------------ Warn yourself with this question: Conclusion, 1. When using arrays, do not forget to initialize them. 2. when copying code in two cases, you must be careful when modifying the variable

Link to the Q & A 11077-find the permutations page Given a 1 ~ The sorting of N can be changed to 1, 2,… through a series of exchanges ,..., N. Given N and K, it is necessary to calculate the number of arrays at least K times to convert them into

Oil Deposits The geosurvcomp geologic survey company is responsible for detecting underground oil deposits. geosurvcomp works with one Large Rectangular Region of land at a time, and creates a grid that divides the land into numerous

Or the longest ascending subsequence... In this question, any soldier in the queue can see the outside team from the left or right side; That is, the left side of a soldier is the ascending subsequence, and the right side is the descending

Question: There are 150000 numbers and 10000 operations. Change the number of I to x each time, and question the number of backward pairs after each operation. Solution 1: Tree array + treap. Each element of the tree array is a tree. In this way,

Csdn is a tough nut to crack. I was swallowed up to solve the problem, Nima, which caused me to rewrite it. A breakthrough in this question is required by each voter.More than half. Therefore, for k = 3, only one suggestion cannot be adopted. I

Use spfa to determine the negative ring. If a node has a negative ring for n times, record it here. #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include

This is a simple string processing problem. You need to determine whether the given string is a text return or a "mirror string ". Retrieval judgment: you only need to judge whether the first and last characters of the string are the same, and then

The classic question of finding the longest common subsequence (LCS) is well planned dynamically.Note that the input string may be an empty string, so do not use cin. My problem-solving code is as follows: #include #include #include using namespace

Question: There are several points on the plane, and the minimum spanning tree is obtained. There are a maximum of 8 packages. Each package has a price and a number of points. Once purchased, the points in the package will be connected to each other.

AlthoughCodeShort, but there are still many places worth learning. The dynamic pattern mainly refers to the state transition equation. Not yet written. For more information, see http://blog.csdn.net/tclh123/article/details/6286833. At the same

This question is very simple. It only requires that the prime factor of a large number be output. You only need to pay attention to the number of long type. My SolutionsCodeAs follows: # Include # include # include # include # include

Uva_674 You can use deep search to solve this problem. You can enumerate the quantity selected for each non-1 nominal value. The remaining nominal value must be set to 1. In order to make full use of the subproblem solution, we can retain all the

Uva_147 Count with DP, the state transition equation is f [I] [J] = sum {f [I] [J-K * A [I]} (J-K * A [I]> = 0, K is an integer), where I represents the I-th nominal value, j Represents the cents with J, and a [I] represents the size of the I-th

    In jugde queue is returned in the afternoon when I am doing a question on the ultraviolet A. It's strange! I checked it from the last 50 submissions... Wipe, a string of all in this status.   The most freezing thing is, ah, ah, I saw a ID:
