This solution iterates the number of set bits times through the loop. For example, if we input 17 then loop will iterate only two times, whereas in former solution (iterative method to count set bits) it would iterate 5 times. C program: Brian Kernighan's algorithm of counting set bits ...

This instruction calculates the number of bits set to 1 in the second operand (source) and returns the count in the first operand (a destination register). Operation¶ Count = 0; For (i=0; i < OperandSize; i++) { IF (SRC[ i] = 1) // i’th bit THEN Count++; FI; } DEST...

如果要计算一个整形中的位数有多少位被置位,我们的第一想法就是循环查找。现在我们可以参考:http://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel unsignedintbits_counter_v4(unsignedintx) {//count bits of each 2-bit chunkx = x - ((x >>1) &0x55555555);//count bits of ea...
