Say you had a long array of chars that are either 1 or 0, kind of like a bitvector, but on a database column. How would you query to know what values are set/no set? Say you need to know if the char 500 and char 1500 are "true" or not. ...
Hi all, What is the difference between BitArray and BitVector 32 structure and what are the advantages of BitVector 32 structure over BitArray? Why is the BitVector 32 structure more efficient than BitArray? Thanks in advance. Jay... ...
What does the CreateMask() function of BitVecto32 do? I did not get what a Mask is. Would like to understand the following lines of code. Does create mask just sets bit to true? // Creates and initializes a BitVector32 with all bit flags set to FALSE. BitVector32 myBV = new BitVector32( 0 ); // Creates masks to isolate each of the...
In an assignment I am currently working on we need to work with bit vectors, but I am very unsure of how to do this in Python. They should be able to be from 4 bits to 20 bits. I have never worked with bit vector before, but I guess that one would one create arrays of unsigned bytes that you manipulated using the usual AND/OR/XOR operati...
Hello guys! Actually this is an interesting topic from programming pearls, sorting 10 digits telephone numbers in a limited memory with an efficient algorithm. You can find the whole story here What I am interested in is just how fast the implementation could be in python. I have done a naive implementation with the module bitvector. T...
Are there any well-known libraries in Java for sparse bit vectors? (And are there guidelines for how sparse is useful to use them vs. java.util.BitSet?) ...
Hi! what's the best way to perform bitwise operations on vector<bool>? as i understand, vector<bool> is a specialisation that uses one bit per boolean. I chose vector<bool> for memory saving reasons. I know that there are some problems with vector<bool> but for my needs it's apropriate. now - what's the most performant way of aplying ...
