Judgement of Undirected Tree
The following was the method to determine an undirected tree: 1. ** Based on Connectedness and Circuit **: - If an undirected graph is connected and does not contain any simple circuits, it can be determined to be an undirected tree. 2. ** Based on the relationship between the number of edges and the number of vertexes (for the undirected connected graph of order n(n'geq2))**: - When the number of edges is (m = n - 1), there are at least two vertexes with degree (1) in the graph (G). At this time, it can be determined that the graph is an undirected tree. 3. ** Based on the uniqueness of the path between the vertexes **: - If the graph T is connected and there is only one simple path between each pair of different vertexes, then T is an undirected tree. 4. ** Based on the situation after the loop and edges are added **: - If there is no simple circuit in the graph, but there is a simple circuit in the graph obtained by adding a new edge between any two non-adjacent vertexes (i.e.,"maximum acyclic-free"), then "T" is an undirected tree. 5. ** Based on the necessity of the connection and edges **: - If the graph T is connected, but no longer connected after deleting any side (that is, every side in T is a bridge), then T is an undirected tree.

The leaves of the undirected tree
In an undirected tree, the leaves referred to the apex with a degree of 1. Undirected trees have some characteristics, such as being connected and not containing any simple circuits. The number of edges m and the number of vertexes n (n>=2) satisfy m = n - 1. According to the relevant theorem, a non-trivial undirected tree has at least two leaves (a point with a degree of 1). In an undirected tree, except for the leaves, the apex with a degree greater than 1 was called a branch point. The Extraordinary Ordinary Life novel is equally exciting.

What is the degree of an undirected tree?
Every apex in an undirected tree has a degree, which is the number of edges connected to it. The nodes in an undirected tree were divided into two types: leaves (degree 1) and branch points (degree greater than 1). For an undirected tree with n vertexes, the total degree is 2(n - 1).

An undirected tree has at least two leaves
Yes, any non-trivial undirected tree (undirected connected graph of order n> 2) has at least two leaf vertexes (vertexes with degree 1 are called leaves). It can be understood in the following way: Let the number of edges of an undirected connected graph G of order n(n> 2) satisfy m = n - 1 (the relationship between the number of edges and the number of vertexes of an undirected tree). According to the handshake theorem and other related principles, it can be inferred that there are at least two vertexes with degree 1 in the graph G, that is, there are at least two leaves.

A non-trivial undirected tree may be a hamilton graph
A non-trivial undirected tree could not be a hamilton graph. An undirected tree is a connected graph without a loop. Its property is the number of edges, m = n - 1 (n is the number of vertexes). The hamilton graph was a circuit that passed through all the points without overlapping. Undirected trees had no circuits, so a non-trivial undirected tree did not satisfy the definition of a hamilton graph. It could not be a hamilton graph.

Every side of a non-ordinary undirected tree is a cut edge
A non-trivial undirected tree has the property that deleting any edge will make the graph no longer connected. According to the definition of cutting edge, if the edge is an edge of the graph, then when the number of connected branches is the number of connected branches, the edge is called the cut edge of the graph. For a non-trivial undirected tree, because removing any edge would no longer be connected, it meant that the number of connected branches increased after removing an edge. Therefore, every edge in the non-trivial undirected tree satisfied the definition of cutting edges, that is, every edge in the non-trivial undirected tree was a cut edge.

Extraordinary undirected graph
The non-trivial undirected graph was a concept in graph theory. In graph theory, a trivial graph was a graph with only one apex and no edges. In contrast, a non-trivial undirected graph is an undirected graph other than a trivial graph. It contains multiple vertexes or at least one edge, or both. For example, when studying some properties of a graph (such as whether it is an Eulerian graph, whether it is a bipartition graph, etc.), the judgment conditions and properties of non-trivial undirected graphs and trivial graphs were often different.

Judgement 42
The 42nd episode of " Judgment " was the finale of the TV series. In this episode, the main characters Qi Heng and Luo Huaigong engaged in a life-and-death struggle. Although Qi Heng had the opportunity to kill Luo Huaigong, he chose to bring him back to court for punishment, demonstrating his firm principles as a judge. Secretary Wu praised Qi Heng and believed that as long as there were judges like him, the rule of law could be realized in Qizhou. In addition, the drama also received a new task. The above was the answer based on the search results provided.
Blazing Judgement
Ruling Flames was the first game in China to be developed based on the alliance chain. It was based on the national IP, Legend of Mir 2. The game realized the digital collection of game props and equipment, opening up a new era of digital collections used in game scenes. Players could purchase digital collectibles from different platforms to use in the game, and some of the virtual items dropped in the game would generate a unique digital certificate that automatically belonged to the player's digital assets. Shuzang China was the leading digital collection distribution platform in China and had many compliance qualifications. Flame Ruling would also achieve the compliance circulation of equipment in the game. The user's game assets would be upgraded to digital assets with ownership and usage rights, which could be circulated on the platform. This game continued the classic gameplay of the Legend series, and at the same time, it added a hidden gameplay, bringing a new gaming experience to the players.
