Looping over the bits one at a time, extracting and adding the low bit, is a simple but often inefficient way to count the number of set bits. You can get the digits in reverse order by repeatedly dividing the integer or the quotient from the previous division by the base (2 or 10), and saving the remainders (into an array or push them onto the stack), which will contain the digits (in reverse order). A:Answer: Anyone can help me? Higher-level languages including C, Java, and Python that have & and >> operations also always guarantee that they work in binary. To get the low bits do a bitwise and with value 15 as this will zero out the high bits. Does MIPS not have a bne instruction?
