Question:
From 0 ~ Room n-1 numbers arrive at room 0 from a starting point, close every time they pass through a door, and ask if they can pass all the doors and reach room 0.
I think the input and output formats of this question are my first time, so I have been reading sscanf for a long time.
Each row corresponds to the room that the current door can reach. If there are duplicates below, there will be blank lines, empty lines here, and numbers in the string one by one should be considered

Question: a jewelry store buys pearls from a pearl wholesaler. The I-price is P [I]. The price of the pearl is Σ (n + 10) * P [I] because the number of unplanted pearls must be increased by 10 during settlement, sometimes the price of cheap pearls
Given an undirected graph, determine whether there is a path from M point back to 0 and travel all sides, that is, the Euler path.
Solution: If the starting point is 0, it is equivalent to whether there is an Euler loop. The condition for
Question: A variety of pearls, each purchase must add 10 to the original quantity. For example, buy 5 pearls with a unit price of 10. The cost is (5 + 10) * 10 = 150. buy 100 pearls with a unit price of 20.The cost is (100 + 10) * 20 = 2200. The
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

Visualization of weight values
After training, the network weights can be visualized to judge the model and whether it owes (too) fit. Well-trained network weights usually appear to be aesthetically pleasing, smooth, whereas the opposite is a noisy image, or the pattern correlation is too high (very regular dots and stripes), or lack of structural or more ' dead ' areas.
