If you count shifting as a bitwise operator, this is easy. You already know how to do it by successive division by 2. x >> 1 is the same as x / 2 for any unsigned integer in C. If you need to make this faster, you can do a "divide and conquer"—shift, say, 4 bits at a time until you reach 0, then go back ... the perfect plate

Web4. Bit Shift operator in Java- Example. Apart from bitwise operators, Java also provides bit shift operators, which can be used to shift bit from one position to another on both left and right side in a number. Java provides three bit shift operator signed left shift operator "<<", signed right shift operator ">>" and unsigned right shift ... WebThe answer by schnaader is correct: . return (bits >>> k) (bits << (32-k)); the first part (bits >>> k) right-shifts the value stored in bits by k bits and 'the third >' ensures that the leftmost bit is a zero instead of the sign of the bits; the second part (bits << (32-k)) left-shifts the value in bits by k-complement number of bits; Now, you have two temporary variables … the perfect plan weddings
