int NumberOfSetBits(int i)
{
i = i - ((i >> 1) & 0x55555555);
i = (i & 0x33333333) + ((i >> 2) & 0x33333333);
return ((i + (i >> 4) & 0xF0F0F0F) * 0x1010101) >> 24;
}
This is the code in order to count the number of set bits.Can any one
explain me how the instructions in this code can be understand??
