Category "xor"

Is bitwise complement of (n-1) equals to (-n)

The following code prints the two odd occuring numbers in an array: #include <iostream> using namespace std; int main(){ int n; cin>>n; int

Optimized way to implement XOR between floats for huge 2D array data

I need to implement xor between floats in python for huge 2D array data (like thousand row by thousand column matrix). I use the following implementation: impor

Why XOR of all subsets of a list have same frequency?

I have a list of numbers a1, a2, a3, a4, a5, ... and so on. If we find XOR of all subsets then I noticed that frequency of each distinct XOR is the same. Exam
