8 bits representing the number 7 look like this: 00000111 Three bits are set. What are the algorithms to d开发者_如何学Goetermine the number of set bits in a 32-bit integer?This is known as the \'Ham
I\'m trying to implement SHA1 in Ruby and in order to do so I need to preform a left rotate through carry. The code I\'ve written seems to work for 1 rotation, but any more than that it fails my tests
Suppose I have x &(num-1) where x is an unsigned long long and num a regular int and & is the bitwise and operator.
I\'m making a class PackedUnsigned1616 which stores two unsigned shorts in one int, and a class PackedSigned1616 which stores two signed shorts in one int. I\'ve read up on bitwise operations, but I\'
I wanted to replace bit/bits (more than one) in a 32/64 bit data field without affecting other bits. Say for example:
I have a large number of boolean fields in my table containing a list of holiday locations. As the data is fetched from the browser by ajax and 开发者_如何学编程I hope to havea lot of mobile users, I\
What\'s the correct way to handle two distinct values being stored in one byte of data. I have a byte that contains two nibbles each containing their own data. I want to read the top nibble and the bo
I have a list of N colors. I need to represent any of those values as a BitArray. If N = 129 to 255tha开发者_运维技巧n, obviously, each color should be represented as a BitArray with Length 8. It is s
Say you have two hashes H(A) and H(B) and you want to combine them. I\'ve read that a good way to combine two hashes is to XOR them, e.g. XOR( H(A), H(B) ).
I\'ve been trying to figure out how to do a nand bitwise operation in assembly but have been unsuccessful.I\'m tried to write a logic gate simulator that will essentially produce this truth table for
