algorithm - how to create a collection with O(1) complexity -

-

I would like to create a data structure or collection, in which there is no problem adding, removing and computing the O (1) complexity Will be. How should I start with elements?

I have thought of a solution: I will use a hashtable and every key / value will be inserted for the pair, I will have only one hash code, that is: my hash code algorithm every time Will generate a unique hash value, so the index to which the value will be stored will be unique (i.e. no collision).

Will this give me o (1) complexity?

Yes, this will work, but as you mentioned, your hashing function should be 100% unique Should you use any kind of dispute resolution as a result of any duplicate. I would recommend linear chaining

Edit: allows for Hashmap size () o (1) access

Edit 2 : Answer to the negligence of illusion is the reason for this: = P

Yes, Hashing is (K) where Kashmir is the Keyeline. Everyone can agree on it, however, if you do not have a complete hash, then you can not only get O (1) time. You claim that you do not need specialty to achieve the o (1) extinction of a particular element. I guarantee you that this is incorrect.

Consider the worst case scenario: Each element hashes for the same thing. You end up with a single linked list because everyone knows that o (1) is not extinction. I hope, as you have said, nobody is dumb enough to make a hash in this way.

The issue is that the specificity of hash is prerequisite for o (1) runtime.

However, however, it is not technically O (1) Big O functionality, using only quantized analysis, you will gain continuous time capability in the worst case scenario. As the article on Wikipedia is outlined on the revised analysis

The basic idea is that one of the worst situations can change the state in such a way that the worst situation has long since Can not be, thus "amortizing" its cost.

It is referring to the fact that some of the load factors can change your hashtable (change in the status of your data structure) to ensure a small possibility of confrontation.

I hope this clears up all this.

I'm new to this I'm writing a clr. stored procedure that can be used to get values ​​used in a calculation Call for another stored procedure for Gives an archived methodology int (I think SqlInt32? Value of the table's value is int) which is then necessary to convert to decimal.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
