Focus on the official account [high-performance architecture exploration], dry cargo for the first time; Reply to [pdf] and get classic computer books for free This article is excerpted from the article: Memory leaks - causes, avoidance, and location This paper summarizes several common ways of memory leakage. Paying attention to these poin ...

Classification of minimum spanning tree 🐖: The minimum spanning tree is generally used for undirected graphs, and directed graphs are rarely used. Method selection: Dense graph: using naive Prim algorithm Sparse graph: using Kruskal algorithm Heap optimized Prim is not commonly used! Plain Prim The general idea can be referred to Dijk ...

XOR and XOR Recognize XOR int a = 7; // At this time, the binary of a is 0111 int b = 13; // At this time, the binary of b is 1101 So now let's turn a XOR b to 10 0 1 1 1 1 1 0 1 ------- 1 0 1 0 Officially, it is the same as 0, but different as 1 Simply remember that you want to add directly without carrying Separate from the same or operat ...

All in one book Stack part 1 http://ybt.ssoier.cn:8088/problem_show.php?pid=1331 it's a very strange prob.I dont know why i cant pass the test in this website while i can pass in sycoj.so i hold the view that its ybt's fault.there's no bugs in my cpp. Click to view the code #include<bits/stdc++.h> #define rep(i,l,r) for(int i=int(l);i&lt ...

Nanchang Institute of technology acm summer training This week I learned the hash table in the data structure and practiced some data structure topics I learned last week Next week, the multi school league will start to learn search and graph theory while making supplementary questions for the competition General hash table Definition of h ...

The following is the main body of this article, and the following cases can be used for reference. Stack chain overview (illustration) The stack can be stored in sequence or chain, which are called sequence stack and chain stack respectively. Sequential stack allocates a continuous space and requires two pointers. base points to the b ...

Advantages of binary tree: It can be accessed very efficiently on the binary tree. Binary tree is very suitable for interval operation. A subtree in a binary tree can be regarded as a sub interval of the whole tree. It is very fast to find the interval maximum, interval sum, interval flip, interval merge, interval split, etc. Binary tree is ver ...

1, Several traversal algorithms of tree 1. Preorder traversal First access the root of T, and then recursively access the root of the subtree. If the tree is ordered, traverse the subtree according to the child's order. The pseudo code for traversing the root of the subtree at position p is: Algorthm preorder(T, p): perform the visit act ...
