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 … WebSep 13, 2015 · I'm not very familiar with all the bit shifting and masks that are involved with the process but I have a vague idea.
