   It works because you can count the total number of set bits by dividing in two halves, counting the number of set bits in both halves and then adding them up. Also know as Divide and Conquer paradigm.

   19 mar 2011 · Depending on how many bits are set on average it may be faster or slower than the kerrigan loop - though probably also depends on the used CPU. Conceptually this works: int num = 0; do { num += input % 2; input = input / 2; } while (input > 0); return num;

   4 lut 2023 · The Brian Kernighan’s algorithm is used to count its set bits of an integer. It only consider the set bits of an integer by turning off its rightmost set bit (after counting it), so the next iteration of the loop considers the next rightmost bit.

   3 lip 2024 · In this article, we will learn how to count the set bits in a given integer in C++. Example. To count the set bits in a number in C++, we can directly use the __builtin_popcount () method provided by the GCC compiler in C++. This function returns the number of set bits in a given unsigned integer.
