WebLet's say that k = 16. Then you can calculate the number of bits set to 1 in a 64-bit number in much fewer actions if you divide the number into blocks of k bits (for k = 16, you need only 4 blocks). use something like a bitset (although if you use it, it might be better to deal with larger number of bits, not 64). → Reply.
