WebDec 28, 2016 · To shift an m bit integer by c bits, I would need at most c bit operations. To expand, shifting right by c bits, is deleting the c most significant bits. Shifting left by c bits, is simply adding c trailing 0s, so all in all c operations. I guess the time complexity of shifting is O ( c) then. – Tobi Alafin. http://map.grauw.nl/articles/mult_div_shifts.php fish sale at petco

"WebShifting is much faster than division. It may be that the author of the C code did optimize the division/multiplication because shifting does the same as dividing/multiplying by 2 (or by powers of 2) but is faster about 100 times on most of the CPUs. But in most modern C compilers this optimization is done by compiler itself. Share " - Bit shifting multiplication
