Este módulo apresenta os conceitos iniciais de árvores binárias de pesquisa. Ele inclui algoritmos de busca, inserção e remoção.

Árvores de pesquisa

Ah! este parágrafo é necessário para que a seção tenha algo a dizer. Vejam! e a fonte é diferente!

Suponha que você tenha um conjunto de elementos a armazenar no seu computador, de forma que possa realizar inúmeras buscas sobre esses elementos. Suponha agora que você utilize, como estrutura de dados para armazenar esses elementos, uma lista encadeada. Como vocês devem lembrar, a complexidade de busca em uma lista encadeada é (no pior caso) O(n), onde n é o número de elementos da lista. Isso ocorre porque precisamos percorrer a lista, no pior caso (caso onde o elemento a ser procurado se encontra no final da lista), do início (cabeça da lista) até o final. E se pudéssemos dar “saltos” nessa procura?

Claro que podemos dar “saltos” em uma procura. Alias, essa é a forma natural de otimizar processos. Para melhor visualizar esse processo, imagine uma busca de um número no intervalo de 0 a 100. Ao invés de iniciar sua busca no 0 e se estender até o 100, você pode testar o médio, 50, e verificar se o número a ser encontrado é maior ou menor. Se for menor, podemos então desprezar todos os números acima de 50 e recomeçar a busca no intervalo de 0 a 50. Esse procedimento deverá se repetir até que o número correspondente seja encontrado. Esse procedimento gerou implicitamente uma árvore de busca, conforme ilustrado na figura .

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
