The system learns graph theory once! Start with this blog!
First, introduce some concepts.
Undirected graph:
G is a connected undirected graph, and the path that passes through each edge of G once and only once is Euler's path.
If the Euler path is

There are M roads between N towns. You can build roads between any 2 towns and ask how many roads need to be built before the N towns can be connected. --> In fact, it is to calculate the number of connected branches, and then subtract 1. Query set

Recently, when I write code in linux, I always need to check the definition and call relationship. It is inconvenient to switch to source insight in windows every time, so I tried ctags + cs.pdf. I only want to quickly view the definition of
There is nothing to say about it. The LCS problem has been played blindly, but I ce twice because I and J are mixed .. Note that LCS can have an interval in the middle, but KMP does not. In addition, don't forget the dichotomy mentioned in the blog
Problem DescriptionProblems in Computer Science are often classified as belonging to a certain class of problems (e.g ., NP, Unsolvable, Recursive ). in this problem you will be analyzing a property of an algorithm whose classification is not known
The number of stones is n, and then the number of stones is m. Each number indicates the number of stones that can be taken each time. One of them must be 1. Two people played games, one of the above m numbers from the rock heap in sequence, took

Notes:When a pointer is passed as a function parameter, it is essentially a "value transfer", that is, a new pointer variable pointing to the address is copied.
Only when the pointer is referenced in the called function can the variable pointed to
