H-tree connected acyclic undirected graph.

The discriminant graph of H- tree, if T is a tree, the necessary and sufficient conditions are (six equivalent definitions) (theorem 14):

(1) T is an acyclic connected graph; (2) Graph T has no loop, m = n-1;

(3) Graph T is connected and m = n- 1.

(4) Figure T has no loop. If you add an edge, you get one and only one cycle;

(5) Graph T is connected, if any edge is deleted, then G is disconnected;

(6) There is only one path between each pair of nodes in graph T. 。

The spanning subgraph of H spanning tree graph G is a tree, which is a spanning tree.

H- weighted connected graph G is a weighted graph with n nodes, and each edge is designated as a positive number, which is called a weighted graph. The sum of the weights of all the edges of the spanning tree T of G is the weight of the spanning tree T, which is denoted as W(T).

Minimum Spanning Tree The spanning tree with the minimum weight.

H- directed tree A directed graph is a tree with edges deleted.

H- root tree and root nontrivial directed tree have exactly one node degree of 0 (the node is the root) and the other node degree of 1, which is the root tree.

H The root tree whose degree of each node is less than or equal to 2 is a binary tree (binary tree); The root tree whose degree of each node is equal to 0 or 2 is a binary complete tree (binary complete tree); A root tree with a degree of 2 for each node is called a regular binary tree.

1 (because it looks like Lu, it looks like a product and looks like a cat's paw).

2 Mo Ao (read the word "Mo Ao" together, which is consistent with the pronunciation of the word "cat")

Also called:,, Hu,, Lao Hu, cat, cat song,, Hu mother and so on.

Describe your lyrics:

"This man looks a little cute, as if he were still a little handsome. Of course, this "handsome" is just barely crowned. There are three reasons: first, I like to laugh. Affectionate people now call it "flowers". Flowers are not cool, those who are not cool are upset, those who are upset are not wise, and those who are not wise are not disabled. Are you handsome with disabilities? Second, I like talking. People who are multilingual now call it "poverty". Poor people are dishonest, dishonest people float, floating people are not brave, and brave people are empty. Empty and handsome? Third, I like thinking. People who think a lot today call it "softness". Those who are soft are not strong, those who are not strong are worried, those who are worried have no ambition, and those who have no ambition are mediocre. Is mediocrity handsome? "

Song-high school composition fragment:

"The sunshine in early spring shuttles between buildings in this big city with golden warmth. It took away the biting cold in winter and left people with infinite reverie about spring. There is a ray of sunshine that seems to care for a place in particular. It did not hesitate to pour its light and heat into an obscure corner on the second floor of an old villa through dusty glass, completely ignoring the darkness and humidity of the surrounding environment. . . "

Song-introduce yourself:

When I was a child, I was very simple. I like squatting in the toilet and singing in the bathtub, so Singing at will basically summarizes my childhood.

When I grow up, I am still simple, and I like to chew words repeatedly in front of the computer, so "Hugh" becomes "Brother Gu Yue".

"Ancient" stands for nostalgia; "Month" stands for affection; "Brother" stands for fighting righteousness, and "owe" stands for #% @ (I haven't decided yet).

Nostalgia makes me fall in love with art, and art can carry good memories; Affectionate let me choose the performance major of Shanghai Theatre Academy, because I am willing to pour my rich feelings into the stage; Loyalty makes me always put my friends in the most important position; #% @ makes me full of curiosity and yearning for life.

This is me, pure me!

Song-let's go.

Album introduction:

Hugh's first solo album "Departure" is a new starting point for his musical journey. The song "To Love", a tearful work, premiered. The album also includes the episode "Dark Clouds" of the annual key drama "Legend of the Condor Heroes"; Directed by Han Han himself, MV and the theme song "Poison" of Rao Xueman's new work "Leaving Songs"; Happy and lively R&; B's humorous work "Her eyes will rain"; It is highly recommended that the youth campus portrayal "The Day of Riding a Bike" and so on, a ten-break work, full of heart and sincerity!

● 2008 is brand-new, starting from the heart, and the top lineup is committed to creating the first work of the leisure music scene.

This new album "Let's Go", the record company has no restrictions on Hugh, so that Hugh can try more possibilities in music. Hugh himself is curious. How many possibilities does Hugh sing? There are as many as three producers of the whole record, and the content is quite rich. So in this album, you can hear explosive rock and lively R &；; B, the majestic China martial arts style, and fresh campus folk songs. Hugh said, "I feel like Transformers in music."

In order to fully explore the multi-faceted plasticity of Hugh's music, the record company specially invited many top musicians-Wang Zhongyan, Xu, Xu, Peng Juxin, Yang Shengliang and Cheng Peng to help out, and made every effort to build a super-strong music lineup and tailor-made many songs for Hugh. Significantly, no matter what style, every song is very nice. As a result, when choosing the opening song, every song was chosen, which made the staff have a headache.

After fierce PK, the song "Go to Love", which finally moved to tears, stood out and became the first hit song. Go to Love is tailor-made for Hugh by Wang Zhongyan, a senior lyricist. In the part of harmony, Huang Yunling, a senior musician, was invited to make a voice in person; The MV of the song was directed and designed by the famous director Ma himself.

Hugh said, "Go to Love" is a song with vivid feeling. Hugh said that at first he thought the song was too painful and it would be a little depressing to sing. But after repeated thinking, he found that behind all kinds of pain, it was actually the surge of courage. It's the first time to try such an explosive song: "Especially the outbreak of C segment is a great challenge. I was a little nervous at first, but the staff said it was a great surprise after listening to it, which made me feel very gratified."

In addition, the new album also includes the episode "Dark Cloud" of the annual key drama "Legend of the Condor Heroes"; Directed by Han Han himself, MV and the theme song "Poison" of Rao Xueman's new work "Leaving Songs"; Happy and lively R&; B's humorous work "Her eyes will rain"; Hugh himself strongly recommends the portrayal of the youth campus "The Day of Riding a Bike" and so on. There are ten Hugh's works at a time, full of heart and sincerity!
