The BitsSet method is a static extension method that calculates the number of bits set to 1 in the binary representation of a given integer. This method is useful for determining the population count or Hamming weight of an integer, which is the number of 1s in its binary form.
To use the BitsSet method, simply call it on an integer value. This method is an extension method, so it can be called as if it were a method on the integer itself.
// Example usage of the BitsSet method int number = 29; // Binary: 11101 int setBitsCount = number.BitsSet(); // setBitsCount will be 4, as there are four 1s in the binary representation of 29
